Fantastic!  So glad it finally worked for you.

Yes, I think there are one or two dependencies not mentioned on the GDC wiki
which I discovered when first trying to build it.  There's certainly an
unmentioned package which is needed for the test suite.

One of these days I'll have to set up a fresh system and try a build on it just
to document what they are.

Yes, though once I discovered the trick of using gcc-snapshot (bad idea, but it
worked:-) I never had any problems patching the sources.  It was just an
annoyance to have to do it.

Thank Iain, who told me about it :-)  Before that, I'd actually been deleting
and re-unzipping the whole gcc-4.8.1 directory, meaning a complete rebuild every
time.  Rebuilding GDC has recently become much quicker for me ... :-)

I know exactly the feeling, I also had a long period of thinking I'd never get
it working.  I'm very happy these instructions were useful to you -- and I have
to in turn thank the various people who helped me back then :-)
