Thank you, Claudio. That's what I thought might be the case (hence my 
previous question ;-) )

BTW, PGDATA *must* be picked up from the environment - initdb uses this 
to pass it to postgres rather than the command line switch because of 
the amazingly brain dead shell mode used by the Windows version of 
popen(), which chokes on multiple quoted strings.

The remaining issue I see which is somewhat related to this is: how do 
we allow an installation path to be set at install time rather than at 
configure time (in the usual Windows way)? And how do we do that and at 
the same time provide for multiple installations on the same machine?
