title: Defined C token file for flex?
body: <p>I want to split a C file into tokens, not for compiling but for analyzing.  I feel like this should be pretty straight-forward, and tried looking online for a defined <code>tokens.l</code> (or something similar) file for flex with all the C grammar already defined, but couldn't find anything.  I was wondering if there are any sort of defined grammars floating around, or if perhaps I'm going about this all wrong?</p>
