malformed option `-A system=unix'

[Nathan Zierfuss]

I just finished bootstraping gcc-3.1.1 on an IBM RS6000
running AIX 4.3.3.0. Everything when fine. It was configured
with the following:

../src/configure
--with-gcc-version-trigger=$WRK/gcc-3.1.1/src/gcc/version.c
--host=powerpc-ibm-aix4.3.3.0 --prefix=$TARGET/gcc/gcc-3.1.1
--with-as=/usr/ccs/bin/as --disable-nls --norecursion

Compilation results in the following error message:

cws 117% ./gcc -v -o ~/hello ~/hello.c Reading specs from
./../lib/gcc-lib/powerpc-ibm-aix4.3.3.0/3.1.1/specs

Any advice would be appreciated.
