[Yhc] Problems installing YHC on Windows XP

We don't support the gcc from MingW, in fact we don't support GCC on
Windows at all. We only support Visual Studio.

All is not lost though, if you do:
> scons build yhc
> scons build libraries

Then download a snapshot from
http://www.cs.york.ac.uk/fp/yhc/snapshot/ and extra yhi.exe into
inst\bin, you'll have a working Yhc installation built mainly from
source, and can hack the Haskell side of Yhc easily enough. I develop
Yhc using this setup on some machines.

We should get GCC/GHC working as C compilers under Windows.

Thanks

Neil
