If we are going to have a Windows port I don't think we should treat it as
a poor cousin.

This information is easily discoverable on MSDN in 5 minutes. The answer
is that you need to call NetUserGetInfo at level 11 to get a user's home
directory. See
http://msdn.microsoft.com/library/en-us/dnucmg/html/ucmgch09.asp and
http://msdn.microsoft.com/library/en-us/netmgmt/netmgmt/netusergetinfo.asp

(Thinks: using this requires linking with NetAPI32.dll - is that a legal
or practical problem for us?)

Also, I strongly recommend that the name be canonicalised - see initdb.c
for an example. Doing this reduces platform-specific code a lot. Windows
is quite able to handle filenames with a forward slash.

(Thinks again: when we have WIN32 done we need to trawl through the code
to try to abstract out as much as possible, so that people who
don't/won't/can't do Windows specific code won't have to bother.)
