Is anyone using the Byte Craft C Compiler?

For anyone who know about this compiler, I have been using version 1.10d
for most of my programs.  I have recently tried their newer version
1.20b.

If I compile the same program on both compilers, version 1.10d (the one
the code
initially written for), the code works, while the one compiled with
version 1.20b does
not work properly.

Errors seem to come from timing and communications with the SCI.  I
would like to
use the newest one because it has better code compression and I can
upgrade
my code each time they come out with a newer compiler.

Anyone ever here of this or come across this before or have any
suggestions?
