_GNU_SOURCE must be defined before including any other (system)
header, so defining it in glib-unix.h (and hoping no one has included
anything else before that) is wrong. And the "#define _USE_GNU"
workaround for this problem in gnetworkingprivate.h is even wronger
(and still prone to failure anyway due to single-include guards).
Fix this by defining _GNU_SOURCE in config.h when building against
glibc. In theory this is bad because new releases of glibc may include
symbols that conflict with glib symbols, which could then cause
compile failures. However, most people only see new releases of glibc
when they upgrade their distro, at which point they also generally get
new releases of gcc, which have new warnings/errors to clean up
anyway.

* glib/gprintf.c
* glib/gnulib/vasnprintf.c: Don't define _GNU_SOURCE on Windows,
as _GNU_SOURCE has unintended side effects when compiling against
newest mingw headers.
svn path=/trunk/; revision=7563
2007-08-22 Cody Russell <bratsche@gnome.org>
* glib/gprintf.c: Document g_snprintf to return "bytes" rather
than "characters".
svn path=/trunk/; revision=5716
2006-05-09 Sebastian Wilhelmi <wilhelmi@google.com>
* glib/gprintf.c, glib/gspawn-win32.c, glib/gutf8.c,
gthread/gthread-impl.c, gthread/gthread-posix.c,
gthread/gthread-win32.c: Use canonical include form for internal
headers. config.h is always there.

Make PLT-reduction work with gcc4, and don't include
everything in galias.h:
* glib/glib.symbols: Group symbols by header and source file.
* glib/makegalias.pl: Protect definitions by the same
preprocessor symbols used to guard the headers. Move
the alias declarations to a separate file which is
produced when calling makegalias.pl -def
* glib/Makefile.am (galiasdef.c): Add a rule to generate this
file.
* glib/*.c: Include galias.h after the other GLib headers,
include galiasdef.c at the bottom.

Fix#147651, reported by Oliver Guntermann:
* glib/gprintfint.h (_g_vasprintf): Don't wrap vasprintf(),
_g_gnulib_vasprintf() in a macro, since they behave
differently wrt. to memory allocation.
* glib/gprintf.c (g_vasprintf): Instead, differentiate
here between the three cases: system vasprintf(),
_g_gnulib_vasprintf(), no vasprintf().
2003-10-05 Matthias Clasen <maclas@gmx.de>
* configure.in: Make the various printf feature test macros
reflect the system printf, even when using the included printf.
In particular, don't force HAVE_C99_SNPRINTF, since g-gnulib.h
needs that test result. (#122973)
* glib/gprintf.c (g_vasprintf): Don't rely on HAVE_VASPRINTF,
directly check for _g_vasprintf.
* glib/gprintfint.h (_g_vasprintf): Only define _g_vasprintf()
if vasprintf() is available.
* glib/gnulib/printf.c (_g_gnulib_vfprintf): Don't write
trailing nul to the file. (#122973)
* acinclude.m4 (AC_FUNC_VSNPRINTF_C99): Make the test
detect non-C99-compliance of AIX 5.1 and Solaris
vsnprintf(). (#122496)
2003-07-12 Matthias Clasen <maclas@gmx.de>
* glib/gprintf.c: Doc additions.
2003-07-12 Matthias Clasen <maclas@gmx.de>
* glib/tmpl/string_utils.sgml: Add a paragraph about string precision, add links to it.
Remove markup which is now handled better by gtk-doc.
2003-06-06 Matthias Clasen <maclas@gmx.de>
* glib/gprintf.[ch]: Synchronize argument names with headers and docs.
(g_vasprintf): An implementation of vasprintf(), code was lifted
from g_strdup_vprintf(). (#112365)
* glib/gstrfuncs.c (g_strdup_vprintf): Just use g_vasprintf().
positional parameters: (#79488)
* glib/gstrfuncs.c:
* glib/gspawn-win32.c:
* glib/gscanner.c:
* glib/gconvert.c:
* glib/gbacktrace.c: Use _g_printf wrappers.
* glib/gutils.c (g_vsnprintf): Simplify, since we can assume C99
snprintf semantics now.
* glib/gmessages.c (printf_string_upper_bound): No longer needed,
since we can assume C99 snprintf semantics now.
(g_logv): Simplify.
* acinclude.m4 (AC_FUNC_PRINTF_UNIX98): New macro to check wether
printf supports SUS positional parameters.
* configure.in: New option --enable-included-printf to force
compilation of trio; otherwise trio is compiled if the system
printf misses either C99 snprintf semantics of SUS positional
parameters.
* glib/Makefile.am (SUBDIRS): Conditionally compile trio.
(libglib_2_0_la_SOURCES): Add gprintf.c and gprintfint.h.
(glibsubinclude_HEADERS): Add gprintf.h.
* glib/gprintfint.h: New private wrapping either system printf
or trio printf variants in _g_printf wrappers for use inside glib.
* glib/gprintf.h: New public header declaring g_printf variants.
* glib/gprintf.c: Corresponding implementations.
* glib/trio/*: New directory, containing the trio-1.9 sources.
* glib/tmpl/string_utils.sgml: Add note on including gprintf.h,
move some docs inline.
* glib/glib-sections.txt: Add g_printf, g_vprintf, g_fprintf,
g_vfprintf, g_sprintf, g_vsprintf.
