Is it just yylex that's causing the problems? FLEX allows you to change
the name of yylex via a macro you can define in the top section of your
scanner file (YY_DECL).

eg
...
%{
#define YY_DECL int yylex_for_scanner_number_one(void)
%}
...
%%
,,,
%%
...


If not, can you make the offending functions static?
