g++ 2.7.2.1 (the version of g++ that ships with FreeBSD 3.x) doesn't understand the -Wsign-compare warning flag. (I guess it's either a gcc 2.8 or an egcs thing.) This causes the build to abort as soon as it hits its first g++-compiled file. Since I just got my fix checked in this afternoon to build with 2.7.2.1 on FreeBSD 3, this is a pity. The simple solution would be to take -Wsign-compare out of the list of g++ warning flags, but that's boring. :-) I've written an autoconf test to find out automatically which -W flags gcc understands. (This also lets me put -Wno-long-long back, for gcc/egcs versions that understand it.)

Reassigning to alecf. I made him aware of this yesterday, so he's working on it.

Fixed this yesterday
