Hi Keith -

I have the GNU tool chain for MIPS built for RTEMS to run under CYGWIN. I used the following versions:

binutils 2.14 (2.15 has problem generating map files),
gcc 3.4.1 (3.2.1 doesn't generate correct code for va_start),
newlib 1.12 (Add -G0 to newlib_cflags for MIPS host in /newlib/configure.host)

As to the error, I'd wonder if the MIPS assembler is actually being used at the point where the error occurs. You should try getting the compiler to list the tools that it is using.
