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   - http://www.cs.princeton.edu/software/lcc/
tcc   - http://fabrice.bellard.free.fr/tcc/

(plus gcc & icc ofcourse)


Others that I know of but have never used include :

sdcc   - http://sdcc.sourceforge.net/
Compaq C for Linux   - http://h30097.www3.hp.com/linux/compaq_c/index.html
Open Watcom   - http://www.openwatcom.org/
vacpp   - http://www-306.ibm.com/software/awdtools/vacpp/
XL C/C++   - http://www.absoft.com/Products/Compilers/C_C++/Linux/XLC/XLC.html

and I'm sure many more exist...
