I've added a few bits. The main problem is the lack of an official autogen package in Cygwin. > > (but blimey it took a long time - about a day on this dual-core > > machine). > > A day ?!

Or where ? Or is that > part of $GCCSDK_INSTALL_CROSSBIN/.. ? Sorry, it's me getting confused about the use of that variable (again). The GCC3.4.6 instructions have GCCSDK_INSTALL_CROSSBIN set to home/riscos/cross/bin so I was looking there.

Yes, sorry that was careless of me.
