	I have been pretty much displeased with the floating point libraries
provided with Aztec C.  They barely perform any better than MS-BASIC on
some benchmarks and are destroyed by True Basic, so I know that something
better is possible.
	Has anyone rewritten the floating point libraries?  I think they
could be made faster by recoding the routines in assembly, and perhaps
using better routines, but I don't know any assembly.
	Has anyone heard any news about Manx doing this?

	Thanks in advance.
