Win32 port

I have copies of Peer Direct's (Jan's company) port of PostgreSQL to
Win32, and SRA's port to Win32, and permission to generate a merged
patch that can be applied to 7.4.

Now that 7.3 is almost complete, I am going to start work on that.  I
will post patches that deal with specific portability issues, like
fork/exec and path separator handling, and once reviewed, apply them to
the main CVS tree for 7.4.
