With gcc trunk, boostrap fails in stage3 with:

The system <math.h> eventually includes <architecture/i386/math.h>, which has:
#define isinf(x)        \
        (       sizeof (x) == sizeof(float )    ?       __isinff(x)     \
        :       sizeof (x) == sizeof(double)    ?       __isinfd(x)     \
                                                                               
:       __isinf (x))
...

extern int __isinff     (float      );
extern int __isinfd     (double     );
extern int __isinf      (long double);

libgcc-math's s_isinf.c, on the other hand, has:
int
__isinf (double x)
{
...
