Yes. Clang fully supports the C language.

No, but Clang has something else that may be exactly what you're looking
for: the Rewriter class. You can use it to rewrite source in place. Take
a look at RewriteObjc.cpp in lib/Rewrite: it's an excellent example of
how to use the Rewriter. It turns Objective-C code into regular old C
(actually, C++) code.

There's no how-to for this, but since so many people have asked this
before, someone should probably write one.
