It is already included in the source file. I think the problem is this:

On Solaris, math.h includes iso/math_c99.h which has the following declaration
for isinf:

/*
 * C99 7.12.3 classification macros
 */
#undef  fpclassify
#define fpclassify(x)   __builtin_fpclassify(x)
#undef  isfinite
#define isfinite(x)     __builtin_isfinite(x)
#undef  isinf
#define isinf(x)        __builtin_isinf(x)
#undef  isnan
#define isnan(x)        __builtin_isnan(x)
#undef  isnormal
#define isnormal(x)     __builtin_isnormal(x)
#undef  signbit
#define signbit(x)      __builtin_signbit(x)

What are those __builtin macros? Does GCC support them?
