mathinline.h

Hello,

If I compile the following program with:

#define _BSD_SOURCE
#define _GNU_SOURCE
#include <math.h>

int main () { return 0; }

with gcc -O2 -pedantic -c math.c I get following error:

/usr/include/bits/mathinline.h: In function `__signbitf':
In file included from /usr/include/math.h:348,
                 from math.c:5:

/usr/include/bits/mathinline.h:117: initializer element for `__u.__f' is not computable at load time
/usr/include/bits/mathinline.h: In function `__signbit':

/usr/include/bits/mathinline.h:127: warning: ANSI C forbids specifying structure member to initialize
/usr/include/bits/mathinline.h:127: initializer element for `__u.__l' is not computable at load time

If I remove _GNU_SOURCE, -pedantic or -O2, it works. I think something goes wrong
here.

Linux is like a Vorlon.  It is incredibly powerful, gives terse,
cryptic answers and has a lot of things going on in the background.
