Troubles building gcc-20010320 for sparc64

[peter]

Hi,..

I tried building the latest gcc snapshot (20010320) on my solaris8 box with
the intention to build 64bit binaries.

I configured ran: 
# ../gcc-20010320/configure --with-prefix=/usr/local/egcs/ --srcdir=../gcc-20010320/ --with-cpu=ultrasparc
# make LANGUAGES="c c++"
# make install

all just fine,..
however when i tried to compile a simple prog with the -m64 switch I got:

# /usr/local/egcs/bin/gcc -m64 -o test test.c
cc1: -m64 is not supported by this configuration

Anybody any ideas on this ? I'm kinda lost as to what I did wrong :(
