Cool, I built an m68k-sun-sunos4.0.3 crosscompiler (gcc 2.6.0) on my
SS2/4.1.3 a few weeks ago (needed to compile ncsa httpd for a customer,
they didn't have enough disk space to build gcc).  I didn't have any
trouble, but I had all of the sun3's include files, and was able to run
the float.h builder on the sun3 itself.

I tried crosscompiling glibc and threw in the towel.  Whats the secret?
Of course, I wasn't trying to do an embedded systems version, I was just
doing the normal glibc.  I ended up stealing the functions 4.0.3's
libc.a was missing from a 4.1.1 libc.a "patch".
