cross compiler cygwin -> ppc-lynx

[Erlo Haugen <elh at terma dot com>]

Dear Sirs, ;-)
I am trying to build a compiler as stated. I am using gcc 4.0 sources.
I am using gcc 3.3.3 as build-compiler. I managed to build binutils without
problems.

This is part of my environment:
PREFIX=/usr/local/lynx
PROCESSOR_ARCHITECTURE=x86
PROCESSOR_IDENTIFIER=x86 Family 6 Model 8 Stepping 6, GenuineIntel
PROCESSOR_LEVEL=6
PROCESSOR_REVISION=0806
TARGET=ppc-lynx-lynx


For gcc I did this:

Copied headers and libs from target to /usr/local/lynx/sysroot/usr...

Ran configure:
$ ../gcc-4.0-20050220/configure --target=${TARGET} --prefix=${PREFIX}
--enable-threads=gnat 
--with-local-prefix=${PREFIX}/${TARGET} --enable-languages=c,ada
--with-sysroot=${PREFIX}/sysroot 
--with-gnu-as --with-gnu-ld  --disable-multilib

No problems, but java, fortran and libstd3++ is unsupported on target.

The I ran 
make
(No parameters)

This resulted in:

Checking multilib configuration...

There! I am lost. Do I have to build runtimes and libs?? I took that from
my target, so shouldn'tit be OK??
