For something really small, check out Lindberg's Foogol. Here's a version
I converted to C89: http://www.t3x.org/files/foogol5.shar.Z

For something more complete, but still much simpler than GCC, have a look
at SubC: http://www.t3x.org/subc/index.html  There's also a book describing
its internals: http://www.t3x.org/reload/index.html  (Yes, I'm the author!)

There are various other small compilers, from very simple ones to
multi-platform optimizing compilers on my home page. Feel free to
look around!
