Comment-out dynamic link function declarations since they are all
 provided by the system.
Should we bother continuing to support non-elf Linux systems??

Change declarations from "struct varlena *" to "text *".
Remove register variables since compiler should do better on its own.

Change NOTICE/NOTICE/NOTICE/WARN elog messages to a single message
 with a few newline/tab breaks embedded in the string. Much cleaner I hope.

 closer to standard behavior.
Substitute "text *" for "struct varlena *" in declarations.

 sigsetjmp as a macro, so gives compiler warning without bracketing.

  o  A new patch that contains the following changes:
        -- The pg_pwd file is now cached in the postmaster's memory.
        -- pg_pwd is reloaded when the postmaster detects a flag file creat()'ed
           by a backend.
        -- qsort() is used to sort loaded password entries, and bsearch() is
           is used to find entries in the pg_pwd cache.
        -- backends now copy the pg_user relation to pg_pwd.pid, and then
           rename the temp file to be pg_pwd.
        -- The delimiter for pg_pwd has been changed to a tab character.

PORTNAME should not be used anywhere anymore...I hope :)
