source tree.  They should all be $PostgreSQL$ of course.

I think this explains the 'implicit declaration of function gai_strerror'
warnings visible in the current buildfarm report from snake: if
sys/socket.h is included again after getaddrinfo.h, the file would
merrily undefine the gai_strerror macro.

variable (this accounts for regression failures on PPC64, and in fact
won't work on any big-endian machine).  Get rid of hardwired knowledge
about datum size rules; make it look just like datumCopy().

the EXEC_BACKEND code on my machines, so hopefully it will fix the
Windows buildfarm members.

This doesn't really matter for ordinary building of Postgres, but it's
useful for automated checks, such as my just-committed pgcheckdefines.

compiler warning, specifically #ifdef or #if defined tests on symbols
that are defined in a file not included.  The results are a bit noisy
and require care to interpret, but it's a lot better than no tool at all.

I'm going to insist on reversion of this entire patch unless pgrminclude
is upgraded to a less broken state, but in the meantime let's get contrib
passing regression again.

so that the test passes with or without OpenSSL.  Marko Kreen

#include lines, mostly of <errno.h> which was added to c.h years ago.

are alphabetically ordered. I believe the tables were correctly ordered in
the past, but some of them had subsequently regressed.

Strip unused include files out unused include files, and add needed
includes to C files.

The next step is to remove unused include files in C files.

is harmless, but it causes a warning with Tru64's cc.

Few cleanups and couple of new things:

 - add SHA2 algorithm to older OpenSSL
 - add BIGNUM math to have public-key cryptography work on non-OpenSSL
   build.
 - gen_random_bytes() function

The status of SHA2 algoritms and public-key encryption can now be
changed to 'always available.'

That makes pgcrypto functionally complete and unless there will be new
editions of AES, SHA2 or OpenPGP standards, there is no major changes
planned.

  fe-auth.c:573: warning: passing argument 1 of 'free' discards qualifiers
  from pointer target type
pg_krb5_authname used to return a (const char *) to memory allocated by
krb. Somewhere along the lines this was changed so that a copy was
made, returned, and freed instead. However the const modifier was never
removed.

- halt.c did not include stdlib.h, thus missed exit() prototype
- Makefile ignores BINDIR for install.
- Makefile calls install with user/group args, thus failing for regular user.

While trying it I noticed that the Makefile does not support VPATH builds ...

it can handle small fillfactors for ordinary-sized index entries without
failing on large ones; fix nbtinsert.c to distinguish leaf and nonleaf
pages; change the minimum fillfactor to 10% for all index types.
