I think it should work with doing the two following things (both):

1/ Change your lexer to generate case-insensitive tokens.

2/ Use the field "tok_match" of the interface with the lexer. Redefining
   it allows you to match some token pattern with the corresponding token.
     See doc (camlp5) in:
       http://pauillac.inria.fr/~ddr/camlp5/doc/htmlc/grammars.html#b:The-lexer-record
   In the example "default_match", change the test "if con = p_con" into
   "if String.lowercase con = p_con".

Don't know if it still works with Camlp4, but you can often use the
Camlp5 documentation even for many Camlp4 features.
