I don't see any particular need to resort to sarcasm here. The fact that > cygwin uses the newlib library for all of its math operations (as you pointed out in your post in the earlier thread) does not necessarily mean that they provided the Standard C header file, just that the math infrastructure code came from newlib. However, poking around for a few minutes in their CVS repository did, in fact, turn up a copy of math.h that looks identical to the one I have here. Thanks for the information. -- William M.
