This situation illustrates why some of us were beating Lawrence L.
over the head with ANSI compatibility issues. If you write most of
your code in conforming C, then you should be able to port it to
another compiler (or even another processor) with minimal effort.
(you will have to do the usual regression testing, of course)

Unfortunately, most things that do something directly useful
are not part of standard C, almost by definition. Extensions
that tend to vary include methods of mixing ASM with C, ways
of dealing with interrupts, directives to control memory space
for given variables, higher level I/O functions, functions such
as delay() etc. And even on the best microcontroller compilers
you'll likely find a certain number of problems, unfortunately,
if you do any serious programming.
