user that he won't be able to build from a CVS pull.  This is exactly the
same treatment we give Bison and Perl, and for the same reasons.

provide a working 64-bit integer datatype.  As recently noted, we've been
broken on such platforms since early in the 8.4 development cycle.  Since
it took nearly two years for anyone to even notice, it seems that the
rationale for continuing to support such platforms has reached the point
of non-existence.  Rather than thrashing around to try to make it work
again, we'll just admit up front that this no longer works.

Back-patch to 8.4 since that branch is also broken.

We should go around to remove INT64_IS_BUSTED support, but just in HEAD,
so that seems like material for a separate commit.

For simplicity, use PG_MAJORVERSION rather than PG_VERSION for creation
of the PG_VERSION file.

overridden in the snapshot build script.  $MAJORVERSION is what it really
wanted anyway, so we can tighten up the parsing of --set-version's argument.

Silences complaints from "make man", and allows these man pages

--only-analyze mode is for _vacuumdb_, not pg_dump.

superfluous include files.

VACUUM FULL was renamed to VACUUM FULL INPLACE. Also added a new
option -i, --inplace for vacuumdb to perform FULL INPLACE vacuuming.

Since the new VACUUM FULL uses CLUSTER infrastructure, we cannot
use it for system tables. VACUUM FULL for system tables always
fall back into VACUUM FULL INPLACE silently.

peculiar variant of UNION ALL, and so wouldn't likely get written directly
as-is, it's possible for it to arise as a result of simplification of
less-obviously-silly queries.  In particular, now that we can do flattening
of subqueries that have constant outputs and are underneath an outer join,
it's possible for the case to result from simplification of queries of the
type exhibited in bug #5263.  Back-patch to 8.4 to avoid a functionality
regression for this type of query.

This patch only supports seq_page_cost and random_page_cost as parameters,
but it provides the infrastructure to scalably support many more.
In particular, we may want to add support for effective_io_concurrency,
but I'm leaving that as future work for now.

Thanks to Tom Lane for design help and Alvaro Herrera for the review.

Also, work around a memory leak in some versions of Perl.

and allow using config.pl to override the defaults. config.pl is removed from
the repository, so changes there will no longer show up when doing diff, and
will not prevent switching branches and such things.

config.pl would normally be used to override single values, but if an
old-style config.pl is read, it will override the entire default configuration,
making it backwards compatible.

In passing, fix the fact that the framework could never deal with more than
one disbled linker warning - because MSVC wants commas between linker warnings,
and semicolons between compiler warnings...
