It was certainly possible then.  I haven't heard anything since, but
in principle, it should still be possible.

The C code generated by the Mercury compiler's high-level C backend
(which is what the pre-generated .c files in the source distribution
use) is pure C (i.e.  it doesn't use any GNU extensions), so that should
definitely work.  (It appears that in the asm_fast grades -- the fastest
of the low-level C grades -- also worked.  And shared libraries as

Setting up Mercury as a cross-compiler is a little bit tricky; it's been
done before for cross-compiling Windows executables using the MinGW GCC
on Linux.  The file README.MinGW-cross describes the details.  I guess
that something similar would work for ARM.
