Re: MIPS cross on Sun problems

["James Sandys-Lumsdaine" <jas_sl at hotmail dot com>]

Found the origin of the listed problems - my make wan't aliased to gmake as 
I thought it would be.  I also found an email saying to use --use-gnu-as and 
--use-gnu-ld.

However, I'm still struggling to get the thing to work.

What headers do I need, if any, for the --with-headers option? Do I pinch 
some SGI CC headers? Do I need to install gcc on an SGI Mips then pinch 
them?

I have tried using SunUnixgcc headers and SGI headers and the whole thing 
falls apart at:

This header business is doing my head in and is not clearly documented 
anywhere that I can find - please help!
