I am looking at java/lang/fdlibm.h and I was wondering if anyone could
explain why this header does not include the system math.h file. I
tried to replicate what Fortran does but it did not work because
fdlibm.h does not include math.h and thus the macros fpclassify and
isfinite are not defined. I think C99 requires these to be macros and
not functions but without including math.h I won't see them.
So why does fdlibm.h include declarations of sin/pow/sqrt/etc. instead
of just including math.h?
