Other compilers do exist.

Over the years I've personally used a few to compile userspace apps
for different projects (though never for compiling the kernel).

Some of the compilers I have personally used for userspace apps on
Linux include ;

lcc -
tcc -

(plus gcc & icc ofcourse)

Others that I know of but have never used include :

sdcc -
Compaq C for Linux -
Open Watcom -
vacpp -
XL C/C++ -

and I'm sure many more exist...
