I haven't compiled on MinGW in quite some time, but I don't know of  
anything
that's changed that would cause problems.

yyfile and lineno are defined in the flex file steve/stevelex.l.  They
are referenced from the bison file steve/steveparse.y as extern  
variables.
I can't really imagine why there would be a problem with this though,
especially if other symbols generated from stevelex.l are being found
(namely yylex).

You might want to inspect the flex generated file steve/stevelex.c to  
make
sure that the variables are in fact getting defined there, or use "nm"
on the object file stevelex.o to see if the symbols are ending up in  
there.
