I use Gnu Make, Bison and GCC when building GDB, and there are a few nits which
could be modified to make this easier to do.

Use $(YACC) in the makefile, so I can say "make YACC='bison -y'".

Make dep.o and pinsn.o dependent simply on dep.c and pinsn.c respectively; the
current dependency on umpteen different files isn't necessary, since dep.c and
pinsn.c will be links to the correct files, and it causes Gnu Make sometimes to
not make dep.o or pinsn.o.

Add extra declarations of static functions in expread.y; when bison is used
instead of yacc, the ordering is different, and several static functions are
used before they are defined.  This elicits annoying warning messages from gcc.

Keep up the great work - I am looking forward to the promised 3.2 features...
