GMP error when building aarch64-rtems-gcc on Mingw64

[Ryan Long]

While building gcc, arg3nexwm1 fails. The error follows

In file included from ../../../gnu-mirror-gcc-348fb9d/gmp/gmp-impl.h:146,
                  from fib_table.c:4:

This is due to GMP_NUMB_BITS not being equal to 32. Has anyone 
encountered this?

Thanks,
