+
+ * setenv.h: Rewritten to cope with systems that have setenv() but not
+ unsetenv().
+ * setenv.c, unsetenv.c: Taken from glibc-2.2.4 with the following
+ modifications:
+
+ 2002-12-11 Bruno Haible <bruno@clisp.org>
+
+ * setenv.c (alloca): Fall back to malloc.
+ (freea): New macro.
+ (setenv): Use freea() to free memory allocated with alloca().
+
+ 2002-11-13 Bruno Haible <bruno@clisp.org>
+
+ * setenv.c (compar_fn_t, __add_to_environ, setenv): Use ANSI C
+ function declarations.
+ * unsetenv.c (unsetenv): Likewise.
+
+ 2002-03-04 Bruno Haible <bruno@clisp.org>
+
+ Portability to AIX 4.3.3.
+ * unsetenv.c: New file, extracted from setenv.c.
+ * setenv.c: Move the unsetenv() function to unsetenv.c.
+
+ 2001-12-20 Bruno Haible <bruno@clisp.org>
+
+ * setenv.c (__add_to_environ): Don't call realloc(NULL,...),
+ use malloc instead. For SunOS4.
+
+ 2001-12-11 Bruno Haible <bruno@clisp.org>
+
+ * setenv.c: Declare alloca.
+ (compar_fn_t): New typedef.
+ (KNOWN_VALUE, STORE_VALUE): Use it.
+
+ * Makefile.am (libfetish_a_SOURCES): Add setenv.c, unsetenv.c,
+ setenv.h.
+
+2002-12-10 Paul Eggert <eggert@twinsun.com>
+
+ Port exclude.c and exclude.h to more non-GNU systems, e.g. Solaris 7.
+ * exclude.h (EXCLUDE_ANCHORED, EXCLUDE_INCLUDE, EXCLUDE_WILDCARDS):
+ Choose values that are less likely to collide with system fnmatch
+ options.
+ * exclude.c (FNM_CASEFOLD, FNM_LEADING_DIR): Define to 0 if not
+ defined (e.g., a pure POSIX system).
+ (EXCLUDE_macros_do_not_collide_with_FNM_macros): Use FNM_PATHNAME
+ instead of FNM_FILE_NAME, for compatibility with pure POSIX sytems.
+
+2002-12-06 Jim Meyering <jim@meyering.net>
+
+ * error.c: Be consistent: change `#ifndef _LIBC' to `#if !_LIBC'.
+
+ Merge in changes from libc's misc/error.c, in preparation
+ for the merge of gnulib's changes back into libc.
+
+ * error.c (_): Define only if not already defined.
+ Move definition to follow all #include directives.
+ Include unlocked-io.h only if !_LIBC.
+ [_LIBC]: Include <libio/libioP.h>.
+ [USE_IN_LIBIO]: Include <libio/iolibio.h>
+ (fflush): Tweak definition to use INTUSE.
+ (putc): Define.
+
+2002-12-05 Paul Eggert <eggert@twinsun.com>
+
+ * alloca.c [defined emacs]: Include "lisp.h".
+ (xalloc_die) [defined emacs]: New macro.
+ (free) [defined emacs && defined EMACS_FREE]: Define to EMACS_FREE.
+ [! defined emacs]: Include <xalloc.h>.
+ (POINTER_TYPE) [!defined POINTER_TYPE]: New macro.
+ (pointer): Typedef to POINTER_TYPE *.
+ (malloc): Remove decl; we now always use xmalloc.
+ (alloca): Use old-style definition, since Emacs needs this.
+ Check for arithmetic overflow when computing combined size.
+
+2002-12-04 Paul Eggert <eggert@twinsun.com>
+
+ Do not generate unlocked-io.h automatically, since it's easier to
+ maintain it by hand.
+
+ * unlocked-io.h: New file, from GNU diffutils,
+ but with proper copyright notice and attribution.
+ * gen-uio: Remove.
+ * Makefile.am: Add copyright notice.
+ (libfetish_a_SOURCES): Add unlocked-io.h.
+ (BUILT_SOURCES, all-local): Remove unlocked-io.h.
+ (DISTCLEANFILES, io_functions): Remove macros.
+ (EXTRA_DIST): Remove gen_uio.
+ (unlocked-io.h): Remove rule.
+
+2002-12-04 Jim Meyering <jim@meyering.net>
+
+ Reflect the fact that stat.c and lstat.c are no longer generated.
+ * Makefile.am (BUILT_SOURCES): Remove stat.c and lstat.c.
+ (DISTCLEANFILES): Likewise.
+ (EXTRA_DIST): Likewise.
+ (all_local): Don't depend on stat.c or lstat.c.
+ (stat.c, lstat.c): Remove rules.
+ (EXTRA_DIST): Remove xstat.in.
+
+ * xstat.in: Remove file. Contents moved into stat.c.
+ * stat.c: New file. Contents mostly from xstat.in.
+ * stat.c: Rework so that it may serve to define rpl_lstat, too.
+ * lstat.c: New file. Simply #define LSTAT and include stat.c.
+
+ * safe-read.c: Rework so that it may serve to define safe_write, too.
+ * safe-write.c: Simply #define SAFE_WRITE and include safe-read.c.
+
2002-12-03 Jim Meyering <jim@meyering.net>
+ * safe-read.c, safe-write.c: Change variable names and comments, but
+ not semantics, to minimize the differences between these two files.
+ (safe_read): Change comment to mention SAFE_READ_ERROR.
+
* safe-read.c (IS_EINTR): Define.
(safe_read): Use IS_EINTR in place of in-function cpp directives.
