Description:
An <stdarg.h> that conforms to C99.

Files:
lib/stdarg.in.h
m4/stdarg.m4

Depends-on:
include_next

configure.ac-early:
dnl Some compilers (e.g., AIX 5.3 cc) need to be in c99 mode
dnl for the builtin va_copy to work.  With Autoconf 2.60 or later,
dnl AC_PROG_CC_STDC arranges for this.  With older Autoconf AC_PROG_CC_STDC
dnl shouldn't hurt, though installers are on their own to set c99 mode.
AC_REQUIRE([AC_PROG_CC_STDC])

configure.ac:
gl_STDARG_H

Makefile.am:
BUILT_SOURCES += $(STDARG_H)

# We need the following in order to create <stdarg.h> when the system
# doesn't have one that works with the given compiler.
