Right.  I said it would be cool, not necessarily possible.  This brings 
up a problem with this utility - the version of headers that it's built 
against is at the mercy of however the cross compiler's set up, not 
necessarily against the one the user really wants.   Maybe we should 
force the user to define a path, and #error if it isn't defined.  This 
path could be added to C_INCLUDE_PATH and then we could do all sorts of 
Makefile trickery.  Just a thought...

Sounds good.  Promises are fun.
