I'm using sdcc on Solaris (for pic processors) since a few years now, but I compiled it with gcc. i did not have compilation problems. If you plan to use sdcc on pics, be careful to access the registers one byte at a time: for memory, the compiler handles larger data types, but do not try to write 16 bits in a pair of registers, as some microchip compiler allows.
