Hey guys

This is my first post so sorry if this is a little basic. I was bugging
some guys on the autoconf lists about this but its not an autoconf
problem. Whats the best strategy for multiple lexers in one program. So
i made a simple lexer

So my Makefile.am is like:

bin_PROGRAMS= myprogram
AM_YFLAGS = -d
myprogram_CFLAGS= -I$(top_srcdir)/include
myprogram_SOURCES= ..... basic_parser.l #rules_grammar.y rules_parser.l

So yeah these are the problems i can compile in this basic_parser.l fine
but adding in this next 2 files causes the problems. This probably due
to my limited knowledge of yacc and lex. But i see some people talk
about the -p flag to change all prefix names of variables and methods.

Then there is also some people show the gdb hack of redefine everything
inside the yacc files.... but how does that work for different lexers.

Or have i got this completely wrong is it that you can create a lexer
that can work for different things, then its just different yacc files
for grammar. But i dont know how to do that.

Anyways thanks loads any help would be awesome to poke me in the right
direction.

- -Phil
