I am currently working on building openlibm against stock copies of <math.h>, instead of the openlibm.h header. It seems that a C compliant <math.h> header can be used as a drop-in replacement for openlibm.h, with the exception that it lacks cpack*(). In FreeBSD SVN r275819 I patched up the math library by replacing cpack*() by CMPLX*(). That way many functions become less tied to the intrinsics of the math library. Make the same change to openlibm.
