I attempted to compile Bro 1.2 on a FreeBSD 6.1 box with yacc installed
and Bro complained of the following:

=========

I installed bison, did a make distclean and recompiled and it
still came up with this same error.

I manually removed parse.cc, did a make and it compiled fine.

It looks like there's a slight bug in the Makefile under src.

distclean-compile:
        -rm -f *.tab.c

This should probably be changed to parse.cc or something to ensure
that the bison outputted file gets removed on a clean.

I don't know why Yacc disliked it, but it seems to work under bison
properly.
