This module appears to be overzealous: `gl_FP_IEEE' just checks for the
host CPU, but on alpha*-linux-gnu, `-mieee' is apparently not needed:
--8<---------------cut here---------------start------------->8---
#include <math.h>
int
main (int argc, char *argv[])
{
return isnan (NAN);
}
--8<---------------cut here---------------end--------------->8---
Compiled with GCC 4.2.4 on Debian GNU/Linux on Alpha, it returns 1.
Or maybe that's a Debian patch that enables `-mieee' by default?
Thanks,
