Yes, it was stock gcc from Debian. I had to do some damage to the debian/rules
stuff, though. In the archtable in dpkg, there is a column that is supposed to
be the GNU architecture. This must be set correctly for gcc to be able to build
this package. For my stuff, I set the dpkg architecture to i386-freebsd, and
the GNU one to i386-freebsdelf. There is also dpkg-architecture under the
scripts directory. It has to be changed separately.

I don't know what this is going to take yet. I'm a bit confused by the sysdeps
directory in glibc. That's where the system dependent stuff is supposed to go,
and it looks like they did some kind of multiple inheritance thing with
Makefiles... Probably going to take me a while.
Most of the GNU packages are trouble-free. Where I've been having the trouble
is with the Debian-specific ones.

Some of them. There are a couple (perl is one) that are setup to only support
linux or hurd in the debian/rules. It takes i386-freebsd and turns it into
i386-freebsd-linux, but it knows to turn i386-hurd into i386-gnu. We get to
add support for freebsd and netbsd.
