The following reply was made to PR c/2381; it has been noted by GNATS.

 I once had a similar problem when trying to compile 2.95.2
 on netBSD.  Perhaps the fix I made then is of help to you
 in here too.  
 
 Please look at http://www.xs4all.nl/~carlo17/gcc/netbsd.html
 NetBSD != solaris8, but I am pretty sure the problem here
 is the equivalent.

>Description:
The following simple program will give an (below) if compiled
with the definition of _XOPEN_SOURCE in place. The code as
expected compiles fine if the #define is commented out.

This is my distillation of the compile issue I'm facing
trying to build ImageMagick-5.30. Note this occurred in
earlier versions of gcc (2.95.2) with eariler versions
of ImageMagick. But this is the first time I have tracked
it down to a simple reproducable piece of code.

IMPORTANT : Late finding - also on Solaris 7 x86 with 2.8.1

$ cat headertest.c

#define _XOPEN_SOURCE  500  /* */

#include <stdio.h>
#include <stdarg.h>

int main( void )
{
  /* printf( "_XOPEN_SOURCE=%d\n", _XOPEN_SOURCE ); */
}
