Re: treecc help required, generated code doesn't compile

You should add the following to the top of expr.tc to make sure that expr.h is 
included into expr.c before the c_skel.c code:

%{
#include "expr.h"
%}

You will also need to add '#include "expr.h"' to the front of expr.l so that 
the definitions in expr.tab.h are compiled correctly.

You may want to check out the treecc/examples directory in the source, as it 
contains compilable samples that may be a bit more polished than the ones in 
the documentation.

Cheers,

Rhys.
