At my request, Doug Lea included modifications to the g++ version math.h that include math-m68881.h, which was previously distributed via gnu.gcc.bug. This version of math.h simply checks to see if you're using the 68881, and, if you are, includes a header file that uses m68881 functions to perform common functions. There are caveats to this approach, and I think they're included in the header file. To get the same functionality from `gcc', simply incant a math.h that checks for _USE_68881_ & include math-m68881.h if it does. The last I heard, these feature will be supplanted by new __builtins that allow similar functionality but allow even greater optimizations. -- Dirk Grunwald -- Univ. of Illinois (grunwald@flute.cs.uiuc.edu)
