We have had very good luck with the Hi Tech C compiler.    There is a
demo of it available at their web site (http://www.htsoft.com).  It is
full ANSI and generates very good code.  It comes with a text based IDE
and a full linker.  I used it with the emulator and it supported source
level debug.

The first release of my product ships today.  I did find a couple of
areas that I had to work around, however.  I had a problem accessing
bits in i/o registers in page 1.  I copied them to a local variable and
examined the bits in there.  I also found that the call sequence to the
library routine that accesses consts is not reentrant.  Therefore, I had
to alter the code in the interrupt routines so they no longer access
consts.  (I simply removed the "const".)

Don't overestimate these few small areas of concern.  All in all, a very
positive result.  And, considering that it is all ANSI C, the result is
very portable as well.
