+
+ ldexp: relax license
+ * modules/ldexp (License): Trivial relax, since the module only

+
+2012-08-02 Stefano Lattarini <stefano.lattarini@gmail.com>
+
+ gnumakefile: better interaction with Automake-NG
+ * modules/gnumakefile [Makefile.am]: The makefiles generated by
+ Automake-NG always contain a definition of VPATH, even in non-VPATH
+ builds (its value being simply '.' in that case). So, in the
+ 'clean-GNUmakefile' rule, to determine whether running under a
+ VPATH setup, compare '$(srcdir)' to '.' rather than checking whether
+ '$(VPATH)' expands to the empty string.
+
+2012-08-02 Carlo de Falco <carlo.defalco@polimi.it> (tiny change)
+
+ base64: Use extern C scope in header file, for C++.
+ * lib/base64.h: Add C++ namespace protection.
+
+2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
+
+ stat-time, timespec, u64: support naive out-of-dir builds
+ * lib/stat-time.c, lib/timespec.c, lib/u64.c:
+ Use '#include "foo.h"', not '#include <foo.h>', when including
+ one's own interface. This works better when configuring with
+ out-of-directory builds, since packages need not add an
+ otherwise-unnecessary -I$(topdir_src)/lib to DEFAULT_INCLUDES.
+
+2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
+
+ utimens: use extern-inline
+ * lib/utimens.c (_GL_UTIMENS_INLINE): Define when including utimens.h.
+ * lib/utimens.h: Add copyright notice, since this is now large enough
+ to copyright. Use _GL_INLINE_HEADER_BEGIN, _GL_INLINE_HEADER_END.
+ (_GL_UTIMENS_INLINE): New macro. Use it instead of 'static inline'.
+ * modules/utimens (Depends-on): Add extern-inline.
+

+ * lib/u64.c: New file.
+ * lib/u64.h: Use _GL_INLINE_HEADER_BEGIN, _GL_INLINE_HEADER_END.

+ * modules/u64 (Files): Add lib/u64.c.
+ (Depends-on): Add extern-inline.
+ (configure.ac): No need to require AC_C_INLINE, since extern-inline
+ does that now.
+ (lib_SOURCES): Add u64.c.
+
+ timespec: use extern-inline
+ * lib/timespec.c: New file.
+ * lib/timespec.h: Use _GL_INLINE_HEADER_BEGIN, _GL_INLINE_HEADER_END.

+
+ extern-inline: new module
+ * modules/extern-inline, m4/extern-inline.m4: New files.
+ This is for better support of 'extern inline' a la ISO C99,
+ with a portable alternative on compilers that do not support
+ C99-style 'extern inline'. Using 'extern inline' shrinks the size
+ of the Emacs executable, when compiled with debugging disabled,
+ which is a typical way that Emacs is built while developing.
