Yes, we moved stuff around in between <float.h> and <math.h> to match what you see on FreeBSD for example.

Since the new format specifiers are processed at run-time, there is nothing to guard in the headers.  The only new routines are a bunch of new MATH$ routines.

People who have been testing the cross-compilers with these new headers have already bumped into compile errors since they didn't guard their homegrown definitions in anticipation of these finally showing up 20 years later.
