Cannot configure rtems-4.5.1-pre3 on Cygwin

[Campbell, Richard D (Contractor-OAR)]

First time poster needs help,


- Untarred i386-rtems-binutils-2.10-3.tar.bz2 and
i386-rtems-gcc-2.95.3-newlib-1.8.2-1.tar.bz2 (/opt/rtems)
- Untarred rtems-4.5.1-pre3.tar into working directory
- PATH=/bin:/usr/bin:/usr/local/bin:/opt/rtems/bin
- /bin/cc is symlinked to /bin/gcc (2.95.3-5 cygwin special)
- autoconf is version 2.13-4
- automake is version 1.4p5-5

cd build-rtems-4.5.1-pre3
../rtems-4.5.1-pre3/configure --target=i386-rtems --prefix=/usr/local/cross

If I create the conftest.c file in a working directory and compile it with
    /opt/rtems/bin/i386-rtems-gcc -o conftest conftest.c
I get the same assembler error message

However
   /opt/rtems/bin/i386-rtems-gcc -o conftest -S conftest.c
creates conftest.s

and
    /opt/rtems/bin/i386-rtems-as conftest.s 
creates an a.out

Is the wrong assembler being executed or what?

Thanks,

Richard Campbell
