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

I have a set of scripts I used to build the MIPS tool chain under CYGWIN. 
The GCC configuration looks like this:

/opt/gcc/gcc-3.4.1/configure \
  --target=mips-rtems \
  --prefix=/opt/mips-rtems \
  --program-prefix=mips-rtems- \
  --with-local-prefix=/opt/mips-rtems \
  --enable-languages=c \
  --with-gnu-as \
  --with-gnu-ld \

If you're interested, e-mail me and I can send you the complete set.

Do you mind me asking? Does tx_mips64 imply you're working with Toshiba
