On Win32 the implementation is simple because the IEEE recommended

Many thanks for your thoughts, Bill.
I'm looking into this issue and would like to ask for some advice.
I have added the following platform dependent functions.
int Parrot_math_isnan(double)
int Parrot_math_finite(double)
On Win32 the implementation is simple because the IEEE recommended
functions _finite and _isnan are supported.
