It can used unchanged, though I don't know if that is a reason to use it.
Having a C preprocessor is definitely a requirement of the LinuxBIOS small C.

To have an idea how small a fairly complete C compiler can get, lookup
tcc.  It can very nearly compile the kernel and the source is only
200K or so.  It currently does not optimize but...
