This pollutes the reserved compiler namespace and breaks applications
trying to do their own feature detection. For instance, this falsely
detects that alloca is not a builtin on gcc:
#include <glib.h>
#if defined(__has_builtin)
# if !__has_builtin(alloca)
# error "wtf glib?"
# endif
#else
/* version-checking to determine alloca existence */
#endif
Instead, define our own g_macro__has_* versions that have the
behaviour that we need.

The files asnprintf.c printf-args.c printf-args.h printf-parse.c printf-parse.h vasnprintf.c vasnprintf.h are taken from the vasnprintf module of the GNUlib package, which can be found at: http://www.gnu.org/software/gnulib/ All files have been modified to include g-gnulib.h. vasnprintf.c has also been modified to include support for long long printing if the system printf doesn't. This code is protected by #ifndef HAVE_LONG_LONG_FORMAT. Code has been added to printf-args.[ch], printf-parse.c and vasnprintf.c to support printing of __int64 values with the I64 format modifier. This is protected by #ifdef HAVE_INT64_AND_I64. The files printf.h printf.c g-gnulib.h have been written by me. printf.[hc] contain implementations of the remaining functions in the printf family based on vasnprintf. g-gnulib.h is included by all source files in order to move all exported functions to the _g_gnulib namespace, replace malloc by g_malloc and make sure that snprintf is only used if it implements C99 return value semantics.
