X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=61c7194612d105be0b93e3f39e909cf16819f9f1;p=gcc.git

acinclude.m4 (GLIBCPP_ENABLE_C99): Add stdio.h checking.


2001-06-10  Benjamin Kosnik  <bkoz@redhat.com>

	* acinclude.m4 (GLIBCPP_ENABLE_C99): Add stdio.h checking.
	Add checking for strtof, _Exit in stdlib.h
	* aclocal.m4: Regenerate.
	* configure.in: Regenerate.
	* include/c_std/bits/std_cstdio.h: Alphabetize lists.
	(snprintf): Put C99 functions into __gnu_cxx namespace.
	(vfscanf): Same.
	(vscanf): Same.
	(vsnprintf): Same.
	(vsscanf): Same.
	* include/c_std/bits/std_cstdlib.h: Alphabetize lists. Put undefs
	for C99 functions within _GLIBCPP_USE_C99 guard.
	(_Exit): Same.
	(strtof): Same.
	(strtold): Same.
	* include/bits/locale_facets.tcc: Check if C99 is enabled.
	* include/c_std/bits/std_cwchar.h (__gnu_cxx): Put undefs within
	C99 guard.
	* include/c_std/bits/cmath.tcc: Formatting tweak.
	* include/c_std/bits/std_cmath.h: Same.
