My main experience with C on PICs has been with C18 and C30.

C18 seems to work correctly, but uses idiotic stack conventions and
subroutine linkage.  This effects overall performance and RAM use, and makes
any assembly code in the same project more difficult and less efficient.
I've talked to Microchip people about this, and they aren't inclined to fix
it any time soon.

C30 seems to be a nice piece of work.  The assembly code I've looked at
actually makes sense most of the time.  If you're stuck having to use C
(yucc), then try to do it on one of the 16 bit PICs like the 24, 30, or 33
series.
