From: "D'Arcy J.M. Cain" <darcy@druid.net>
Subject: [HACKERS] libpq/pqcomm stuff and Solaris byte orderI decided to go ahead with the required changes since no one else seemsto. I don't guarantee that it is perfect but with these changes thepackage actually compiles. While I was at it I added to the SparcSolaris header to define the byte order. Note that NetBSD sets thisin the system headers so it wasn't required there.In particular, someone may want to check whether I removed the correct84 lines from backend/libpq/pqcomprim.c.
