I'm afraid you'll have to process include files (I can't imagine
another solution). If you are interested on a C grammar for yacc and
lex, you can download it from my ftp-site:
In that directory you can find a C grammar for yacc and lex which
does not solve the "typedef problem" (I ftped it from
primost.cs.wisc.edu , file c-grammar.gz, and its author is Jeff Lee
jeff@gatech). The files are scan.l.bak and gram.y.bak .
I made some changes to these files to fix the "typedef problem"
(didn,t fix the "include problem", sorry) and I added some extra
actions to build a linked (linked) list of all tokens and lexemes of
the source program. These actions could be used to write something
like a pretty printer (or to build an indenting tool). There is no
documentation and no comments (except a few ones in spanish), but I
think you would have no problem understanding it (if so, please email
me and I will help you).
Hope this helps!
