[Rd] Problem cross-compiling on Ubuntu

[Harry Southworth]

Thanks to everyone who responded. I should now have enough options to
make progress.

The Windows tools have been updated since the last time i tried, so
I'll have another go.

I noticed the 2.6.0/2.7.1 discrepancy, updated everything, and found
it was still there. Since the problem I'm having seems pretty basic
(missing .h files), I thought that first getting the headers and then
seeing if the discrepancy matters would be a reasonable approach.
Maybe not, though.

Anyway, once more, thanks to everyone who responded.
