I'm not porting any GUI (too many differences).  I was just wondering
what shell commands might be wanted by users that only use libpq to
connect to the server.

No bash compatible shell, no 'sed' or 'chmod' or many others.

This is the changes I think has the most chance of affecting anyone
else.

Most of the other changes where to do with which code to compile, WIN32
code or Linux code.  All under compile defines.

How often does the code for libpq change, making older revision of libpq
not work with newer version of the database server?
Currently I an using a libpq compiled from 7.4.2 code with the database
server version 7.4.6.  I expect that the communication protocol between
libpq and the database server would be quite stable.
