Yes, 64bit Fedora.

I did configure using the --host=i386 flag, but I'll do it your way. ;)

Now I'll make a record of what I've tried:

cd gnumach
autoreconf --install

cd ../mig
autoreconf --install

cd ../gnumach-build
./gnumach/configure --prefix= --host=i686-unknown-linux-gnu
make DESTDIR=~/gnu install-data

cd ../mig-build
GNU=~/gnu
TARGET_CPPFLAGS=-I"$GNU"/include ../mig/configure --prefix="$GNU" 
--host=i686-unknown-linux-gnu
make all install

cd ../gnumach-build
CPP='gcc -m32 -E -x c -undef -ansi' CC='gcc -m32' LD='ld -melf_i386' 
./gnumach/configure --host=i686-unknown-linux-gnu

Then I installed glibc-devel.i686 and ./configure stopped complaining 
about a non-functioning "gcc -m32".


Now I get a weird error when I run "make gnumach.gz":

Hm, There is no "machine" directory in the repo. I'm still pretty much 
a noob, so I'm not sure how to debug this.

Thanks again for the help.
