compiling gcc-4.0.2 on solaris 9

["Douglas B. Jones" <douglas at gpc dot edu>]

I am on:

SunOS hostname 5.9 Generic_118558-14 sun4u sparc SUNW,Sun-Blade-1500.
I try to do a bootstrap with the following using gnu make 3.80:

mkdir objectdir;cd objectdir
CC="cc -xildoff -xarch=v9"
../gcc-4.0.2/configure
make bootstrap

I get the following errors:

stage1/xgcc -Bstage1/ -B/usr/local/sparc-sun-solaris2.9/bin/   -g -O2 -DIN_GCC   -W -Wall -Wwrite-strings -Wstrict-prototypes

I am new to the sun environment, so any help would be appreciated. Thanks!
