I don't see any particular need to resort to sarcasm here.  The 
fact that

(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.
