+ pipe2: decouple from binary-io a bit
+ This is for Emacs, which needs pipe2 but not binary-io.
+ * lib/pipe2.c [!GNULIB_BINARY_IO]: Don't include binary-io.h.
+ * modules/binary-io (Depends-on): Add module indicator.
+
2013-07-03 Eric Blake <eblake@redhat.com>
mgetgroups: relax license to LGPLv2+
nproc: relax license to LGPLv2+
* modules/nproc (License): Change from LGPLv3+.
+ bootstrap: honor --no-git
+ * build-aux/bootstrap: Don't even try to use git when user is
+ pointing to a static checkout.
+
+2013-06-23 Paul Eggert <eggert@cs.ucla.edu>
+
+ ignore-value: port to gcc -pedantic
+ * lib/ignore-value.h (ignore_value):
+ Port to gcc -pedantic, by using __extension__.
+ Reindent as per usual gnulib style nowadays.
+ Simplify GCC version check.
+
+2013-06-21 Paul Eggert <eggert@cs.ucla.edu>
+
+ extern-inline: port to gcc -std=c89
+ * m4/extern-inline.m4 (gl_EXTERN_INLINE):
+ Do not use __gnu_inline__ if pedantic and pre-C99.
+
+2013-06-18 Paul Eggert <eggert@cs.ucla.edu>
+
+ doc: document extern-inline
+ * doc/extern-inline.texi: New file.
+ * doc/gnulib.texi (alloca-opt): Include it.
+ * m4/extern-inline.m4: Move some comments to documentation,
+ and others closer to what they describe.
+
+ doc: chatter less
+ * doc/Makefile (NEWEST_GNULIB_TEXI_FILE): New macro.
+ (updated-stamp): Use it. This causes 'make' to output just
+ one file name rather than zillions.
+
+ fflush, fseeko: port to musl cross-compiles
+ * lib/fseeko.c (fseeko): Assume that fflushing stdin works if
+ on some implementation that (1) is not known to be buggy,
+ (2) claims conformance to POSIX.1-2008 or later, and (3) is being
+ cross-compiled to so we can't easily check for lack of
+ conformance. This is for cross-compiling to musl.
+ Reported by Rich Felker in
+ <http://lists.gnu.org/archive/html/bug-gnulib/2013-06/msg00043.html>.
+ * m4/fclose.m4 (gl_FUNC_FCLOSE):
+ * m4/fflush.m4 (gl_FUNC_FFLUSH):
+ * m4/fseeko.m4 (gl_FUNC_FSEEKO):
+ Adjust to above change.
+ * m4/fflush.m4 (gl_FUNC_FFLUSH_STDIN): Set gl_cv_func_fflush_stdin
+ to 'cross', not to 'no', when cross-compiling. AC_DEFINE
+ FUNC_FFLUSH_STDIN to 1, 0, -1 if fflushing stdin is known to work,
+ known not to work, or unknown.
+
+2013-06-15 Paul Eggert <eggert@cs.ucla.edu>
+
+ msvc-inval: port to mingw-w64
+ * lib/msvc-inval.c (gl_msvc_invalid_parameter_handler):
+ Use __cdecl, not cdecl, for mingw-w64. Reported by LRN in
+ <http://lists.gnu.org/archive/html/bug-gnulib/2013-06/msg00039.html>.
+
2013-06-11 Paul Eggert <eggert@cs.ucla.edu>
getcwd-lgpl: port to Tru64
if OSF/1, since otherwise Cygwin breaks, and it doesn't seem to
be needed on Solaris either.
* lib/sys_time.in.h [_CYGWIN_SYS_TIME_H]:
- Simply delgate to the system <sys/time.h> in this case.
+ Simply delegate to the system <sys/time.h> in this case.

+@section Extern inline functions
+
+@cindex extern inline
+@cindex inline
+
+The @code{extern-inline} module supports the use of C99-style
+@code{extern inline} functions so that the code still runs on pre-C99
+compilers.
+
+C code ordinarily should not use @code{inline}. Typically it is
+better to let the compiler figure out whether to inline, as compilers
+are pretty good about optimization nowadays. In this sense,
+@code{inline} is like @code{register}, another keyword that is
+typically no longer needed.
+
+Functions defined (not merely declared) in headers are an exception,
+as avoiding @code{inline} would commonly cause problems for these
+functions. Suppose @file{aaa.h} defines the function @code{aaa_fun},
+and @file{aaa.c}, @file{bbb.c} and @file{ccc.c} all include
+@file{aaa.h}. If code is intended to portable to pre-C99 compilers,
+@code{aaa_fun} cannot be declared with the C99 @code{inline} keyword.
+This problem cannot be worked around by making @code{aaa_fun} an
+ordinary function, as it would be defined three times with external
+linkage and the definitions would clash. Although @code{aaa_fun}
+could be a static function, with separate compilation if
+@code{aaa_fun} is not inlined its code will appear in the executable
+three times.
+
+To avoid this code bloat, @file{aaa.h} can do this:
+
+@example
+/* aaa.h */
+/* #include any other headers here */
+#ifndef _GL_INLINE_HEADER_BEGIN
+ #error "Please include config.h first."
+#endif
+_GL_INLINE_HEADER_BEGIN
+#ifndef AAA_INLINE
+# define AAA_INLINE _GL_INLINE
+#endif
+...
+AAA_INLINE int
+aaa_fun (int i)
+@{
+ return i + 1;
+@}
+...
+_GL_INLINE_HEADER_END
+@end example
+
+@noindent
+and @file{aaa.c} can do this:
+
+@example
+/* aaa.c */
+#include <config.h>
+#define AAA_INLINE _GL_EXTERN_INLINE
+#include <aaa.h>
+@end example
+
+@noindent
+whereas @file{bbb.c} and @file{ccc.c} can include @file{aaa.h} in the
+usual way. C99 compilers expand @code{AAA_INLINE} to C99-style
+@code{inline} usage, where @code{aaa_fun} is declared @code{extern
+inline} in @file{aaa.c} and plain @code{inline} in other modules.
+Pre-C99 compilers that are compatible with GCC use GCC-specific syntax
+to accomplish the same ends. Other pre-C99 compilers use @code{static
+inline} so they suffer from code bloat, but they are not mainline
+platforms and will die out eventually.
+
+@findex _GL_INLINE
+@code{_GL_INLINE} is a portable alternative to C99 plain @code{inline}.
+
+@findex _GL_EXTERN_INLINE
+@code{_GL_EXTERN_INLINE} is a portable alternative to C99 @code{extern inline}.
+
+@findex _GL_INLINE_HEADER_BEGIN
+Invoke @code{_GL_INLINE_HEADER_BEGIN} before all uses of
+@code{_GL_INLINE} in an include file. If an include file includes
+other files, it is better to invoke this macro after including the
+other files.
+
+@findex _GL_INLINE_HEADER_END
+Invoke @code{_GL_INLINE_HEADER_END} after all uses of
+@code{_GL_INLINE} in an include file.

-Don't assume that @code{mmap} either works on all files or fails
-for all files. It may work on some files and fail on others.
+If you use @code{mmap} to read or write files, don't assume it either
+works on all files or fails for all files. It may work on some files
+and fail on others.
The proper way to use @code{mmap} is to try it on the specific file for
which you want to use it---and if @code{mmap} doesn't work, fall back on
@example
--prefix --exec-prefix --bindir --sbindir --libexecdir --sysconfdir
---sharedstatedir --localstatedir --libdir --includedir --oldincludedir
+--sharedstatedir --localstatedir --runstatedir

@findex verify_expr
-The @samp{verify} module supports compile-time tests, as opposed to
-the standard @code{assert} macro which supports only runtime tests.
-Since the tests occur at compile-time, they are more reliable, and
-they require no runtime overhead.
+This module provides a header file @file{verify.h} that defines
+macros related to compile-time verification.
-This module provides a header file @file{verify.h} that defines two
-macros: @code{verify (@var{V})} and @code{verify_expr
+Two of these macros are @code{verify (@var{V})} and @code{verify_expr
(@var{V}, @var{EXPR})}. Both accept an integer constant expression
argument @var{V} and verify that it is nonzero. If not, a compile-time error
results.
+These two macros implement compile-time tests, as opposed to
+the standard @code{assert} macro which supports only runtime tests.
+Since the tests occur at compile-time, they are more reliable, and
+they require no runtime overhead.
+
@code{verify (@var{V});} is a declaration; it can occur outside of
functions. In contrast, @code{verify_expr (@var{V}, @var{EXPR})} is
an expression that returns the value of @var{EXPR}; it can be used in
ordinary member declaration. Second, they require the programmer to
specify a compile-time diagnostic as a string literal.
-Here are some example uses of @code{verify} and @code{verify_expr}.
+The @file{verify.h} header defines one more macro, @code{assume
+(@var{E})}, which expands to an expression of type @code{void}
+that causes the compiler to assume that @var{E} yields a nonzero
+value. @var{E} should be a scalar expression, and should not
+have side effects; it may or may not be evaluated. The behavior is
+undefined if @var{E} would yield zero. The main use of @code{assume}
+is optimization, as the compiler may be able to generate better code
+if it assumes @var{E}. For best results, @var{E} should be simple
+enough that a compiler can determine that it has no side effects: if
+@var{E} calls an external function or accesses volatile storage the
+compiler may not be able to optimize @var{E} away and @code{assume
+(@var{E})} may therefore slow down the program.
+
+Here are some example uses of these macros.
@example
#include <verify.h>
even when T is narrower than unsigned int. */
#define MAX_UNSIGNED_VAL(t) \
((T) verify_expr (0 < (T) -1, -1))
+
+/* Return T divided by CHAR_MAX + 1, where behavior is
+ undefined if T < 0. In the common case where CHAR_MAX
+ is 127 the compiler can therefore implement the division
+ by shifting T right 7 bits, an optimization that would
+ not be valid if T were negative. */
