[Bro] Strange Bro build problem with yacc/bison

[frenzy at frenzy.org]

I am getting this on a FreeBSD 5.4 system also. It seems that
make_parser.pl is not getting called to interpret the parse.y file.
If I run 'make_parser.pl byacc' manually, then the build completes.

It's been awhile since I've played with autoconf/automake.

The conflict appears to be somewhere in the following two entries:

broparse.h parse.cc: parse.y
        $(YACC) $(YFLAGS) parse.y
        @sed '/extern char.*getenv/d;s/yylex/brolex/' <y.tab.c >parse.cc
        @mv y.tab.h broparse.h
        @rm y.tab.c

parse.y: parse.in make_parser.pl
        @rm -f parse.y
        perl -w $(srcdir)/make_parser.pl "$(YACC)"
        chmod -w parse.y

Thanks,

Randy
