You could try building the parts you want explicitly:

	make xgpc gpc1 gpc-cccp

Most recent GPC versions should accept GCC_FOR_TARGET, the compiler used
to build libgcc.a and libgpc.a

	make CC=<your_cross_gcc> HOST_CC=<native_gcc> \
		GCC_FOR_TARGET=<cross_gcc_for_target> ...

The latest GPC beta has part of the RTS in Pascal, but I just hacked in
support for GPC_FOR_TARGET :-) Just wait for the next beta.

Needless to say you need various cross-compilers ready and installed to do
all of this, but you knew that or you wouldn't try canadian cross.

I crossbuild native cygwin32 GPC compilers from Linux regularly.

Hope this helps,

JJ

to land, and it could be dangerous sitting under them as they fly
overhead.  -- RFC1925.
