>Description:
Defining _XOPEN_SOURCE and _XOPEN_SOURCE_EXTENDED before including
signal.h makes it declare a couple of functions that have parameters
of type siginfo_t.  It does however not define siginfo_t...

This breaks some programs, e.g. gcc-current.

>How-To-Repeat:
pc20> cat > foo.c 
#define _XOPEN_SOURCE
#define _XOPEN_SOURCE_EXTENDED 1
#include <signal.h>
pc20> gcc -c foo.c
