If you want small and fast use lcc.

Unfortunately it's not completely free (some weird license), doesn't
really support real inline assembly and generates rather bad code compared 
to gcc.

I'm still looking forward to Open Watcom (http://www.openwatcom.org) - 
they are near self hosting on Linux. The inline assembly is very VC++ style 
though; very different from gcc and worse you have to write it in
Intel syntax.

Another alternative would be TenDRA, but it also has no inline assembly
and it's C understanding can be only described as "fascist".

If you don't care about free software you could also use the Intel
compiler, which seems to be often faster in compile time than gcc now
and can already compile kernels.
