Subject: Re:   New: Missing __builtin_fpclassify

As previously discussed, this builtin would either need to be used in the 
form

#define fpclassify(x) __builtin_fpclassify(FP_INFINITE, FP_NAN, FP_NORMAL,
FP_SUBNORMAL, FP_ZERO, (x))

or would need GCC to be configured with target-specific information about 
FP_*, since the values of the FP_* macros are not standardized.
