[nhc-bugs] Building nhc98 on Windows 2000

I've had half an eye on this discussion... just a couple of things to
add:

'ghc -v' on 5.00 and 5.02 (and later versions) will tell you where the
package config file is, and the rest of the info can be extracted from
that.  However, you do know that we're planning to move to binary
interface files, right?  Perhaps we should rethink how hmake gets hold
of its info about libraries - what exactly does it need to know?

I don't know whether Sigbjorn plans to continue supporting this route -
Sigbjorn? =20
