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

Files:

Depends-on:

|
|
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 gl_PROG_CC_C99 arranges for this. With older Autoconf gl_PROG_CC_C99
|
|
dnl shouldn't hurt, though installers are on their own to set c99 mode.
