This is a tokenizer, easily written with a tool such as lex/flex.  Almost
as easily coded by hand.

That's a problem.  func(x) is actually four tokens - 'func', '(', 'x'
and ')'.  While it's possible to write the tokenizer rules so that
'func(' is a single token, you'll rarely see this done in practice.
It's also not really correct to call 'func' the function - what's the
"function" in this C snippet:

   ((*((struct foobar *) x)).y(2))->z()
