I really like CCS's "PCM" compiler for 16Cxx pics.  Works great, and
doesn't have all those nasty limitations.  Want multi-dimensional arrays?
No problem!  Want more than two arguments for a function?  No problem!
Check it out:

Mark, the author, knows his stuff.  It's much better than any other C
compiler I've seen for the PIC.  And Cheryl (an incredibly beautiful young
woman, but married) is amazingly knowledgeable for a
secretary/receptionist.  I was extremely impressed with the compiler's
performance and exceptionally pleased with their customer support.  AND...
it's not expensive!
