>Description:
Error during compilation:

sscanf.c:31: warning: conflicting types for built-in function `sscanf'
sscanf.c: In function `sscanf':
sscanf.c:37: error: `va_start' used in function with fixed args
../stdio-common/_itoa.h: At top level:
../stdio-common/_itoa.h:40: warning: inlining failed in call to `_itoa_word'
../stdio-common/_itoa.h:76: warning: called from here
make[2]: *** [/other/lib/glibcOBJ/stdio-common/sscanf.o] Error 1
make[1]: *** [stdio-common/subdir_lib] Error 2
make: *** [all] Error 2

>How-To-Repeat:
	I follow the normal installation procedure:
	mkdir glibOBJ
	cd glibOBJ
	../glib-2.3.2/configure --enable-add-ons
	make
>Fix:
	I modify the file sscanf.c
	(I hope that my modify don't damage something)

	Original:
		int
		sscanf (s, format)
			 const char *s;
			 const char *format;
		{
		  va_list arg;
		  int done;

		  va_start (arg, format);
		  done = __vsscanf (s, format, arg);
		  va_end (arg);

		  return done;
		}
		libc_hidden_def (sscanf)

	Modified (add ",..." in function argument):
		int
		sscanf (const char *s, const char *format, ...)
		{
		  va_list arg;
		  int done;

		  va_start (arg, format);
		  done = __vsscanf (s, format, arg);
		  va_end (arg);

		  return done;
		}
		libc_hidden_def (sscanf)
