I don't know what you call 'yacc'.  What we mean by "Bison is compatible with 
YACC", is Bison implements the features of YACC as specified by POSIX 
(  There is 
no such thing as -P.

However, Bison features different skeletons (read "backends"), which probably 
correspond in spirit with -P, but is certainly not compatible in any way with 
your yacc.
