Thanks Simon,
I believe you're correct.
I thought I'd looked at this previously - it seemed like an obvious
potential problem - however I obviously had not looked carefully enough.

I can now compile R on OpenBSD alpha and i386.
Unfortunately there still seems to be a problem on the alpha, which looks
like a 32/64 bit issue. The linker complains when loading the ts.so library
in particular about symbol size mismatching.

I'll keep looking to see how to sort this out.

I've reviewed my previous OpenBSD patches, which now look like a horribly
clumsy way of fixing the shared library naming problem, and I see they were
mangled in the conversion to html.

For the benefit of anyone else using OpenBSD, here are my revised patches
(just need to get R on the alpha working properly):
