During the cleanup of the _MSC_VER versions (commit
38d8dce61fff09daae0edb6bcdd42b0c7f10ebcd), I found it useful to use
-Wundef, but that resulted in a bunch of gratuitous warnings. Here is a
patch to fix those. Most of these are just stylistic cleanups, but the
change in pg_bswap.h is potentially useful to avoid misuse by
third-party extensions.
