emulate computed fields.  I suppose this is why the Berkeley boys made
it work that way in the first place, but the docs never said so anyplace.

upgrade tags to rc4

syntax apparently does not work for all toolchains on that platform.

request packet, use pqReadData().  This has the same effect since
conn->ssl isn't set yet and we aren't expecting more than one byte.
The advantage is that we will correctly detect loss-of-connection
instead of going into an infinite loop.  Per report from Hannu Krosing.

discussion on pgsql-hackers-win32 list.  Documentation still needs to
be tweaked --- I'm not sure how to refer to the APPDATA folder in
user documentation.

consistent.  On Unix we now always consult getpwuid(); $HOME isn't used
at all.  On Windows the code currently consults $USERPROFILE, or $HOME
if that's not defined, but I expect this will change as soon as the win32
hackers come to a consensus.  Nothing done yet about changing the file
names used underneath $USERPROFILE.

subroutine that can hide platform dependencies.  The WIN32 path is still
a stub, but I await a fix from one of the win32 hackers.
Also clean up unnecessary #ifdef WIN32 ugliness in a couple of places.
