Help! - Compilation error for mips-rtems tools under Cygwin

Having downloaded what appears to be the latest tools
sources for mips-rtems under Cygwin ( binutils 2.15,
gcc 3.3.3, and newlib 1.13.0 ), binutils built and
installed fine, but during build of gcc, got an
assembler error on a -G option as being unrecognized.
I have included some of the output here with hopefully
enough to identify where this is happening in the
makefile. I am attempting to build in accordance with
the RTEMS doc "Getting Started with RTEMS for C/C++
Users", Edition ss-20030411, dated 27 January 2003,
Appendix A, section A.2.4. I have successfully
completed the steps down to A.2.4.5 "make cross".
Also, how do I use configure to tell the tools to
build for big-endian MIPS? This seems to be building
for a little-endian target, by the mips3/.../el
directory references. configure --help didn't reveal
any secrets on this.

Am I even heading down the right road with this??? Or
should I be trying to use a different set of tools for
building under Cygwin?
