64-bit Ruby on Solaris?

Hi all,

Solaris 9
gcc 3.3.1
Ruby 1.8.1 p2
Sunblade 100, UltraSparc IIe

As usual, I'm playing with things I don't truly understand.  Anyway, I
thought I'd try building 1.8.1 p2 as 64 bit since I've upgraded my
compiler since last time.

After running configure, I manually added "-m64 -mcpu=ultrasparc" into
the CC line of the Makefile.  I seemed to get further this time, and
died with a different error:

gcc -m64 -mcpu=ultrasparc -g -O2  -I. -I. -c io.c

I tried messing with the LDFLAGS and CFLAGS settings as well but no
luck.  Any ideas?
