Its a very small patch to enable stabs for gcc.  Alternatively, you can
get pgcc, which has support for stabs already.

bison 

'-l'
'--no-lines'
Don't put any '#line' preprocessor commands in the parser file.
Ordinarily Bison puts them in the parser file so that the C
compiler and debuggers will associate errors with your source
file, the grammar file. ...

Note that to use this you should not enable it until your sources compile
OK, as compiler errors will be reported in the .c file as well.
