Thanks largely to Ian Lynagh, GHC now has a BuildBot infrastructure to automate 
nightly builds on multiple platforms.  This replaces the old set of shell 
scripts that we used to run nightly builds; now adding new clients to the setup 
is relatively easy, instructions are here:

So far we have various Windows builds running, and I'll be moving over the 
existing Linux nightly builds in due course.

If you have a spare machine or a machine that is idle overnight, and you'd like 
to use it to run automated GHC builds, then please take a look at the above page 
for how to get started.  We especially need platforms that we don't use 
regularly (i.e. not Windows or Linux/x86/x86_64).

Cheers,
