Does anyone have trouble creating a parser with flex and FlexLexer.h together
with a 'regular' grammar file from bison. When I link the two files in Visual
C++ 60 I get a linker error that the bison obj file can not find yylex??? Is
there a way to re-define yylex so the bison part actually recognizes the
wrapper classes in FlexLexer.h???? Do I need to write my own parser wrapper
class??


Appreciate any suggestions!
Thanx,
Hans
