The point that you need parentheses for non-constant expressions apparently
needs to be brought out a bit more clearly, per bug #6315.

Since record[] uses array_in, it needs to have its element type passed
as typioparam.  In HEAD and 9.1, this fix essentially reverts commit
9bc933b2125a5358722490acbc50889887bf7680, which was a hack that is no
longer needed since domains don't set their typelem anymore.  Before
that, adjust the logic so that only domains are excluded from being
treated like arrays, rather than assuming that only base types should
be included.  Add a regression test to demonstrate the need for this.
Per report from Maxim Boguk.

Back-patch to 8.4, where type record[] was added.

Per Emmanuel Kasper, sysctl works fine as of NetBSD 5.0.

DST law changes in Brazil, Cuba, Fiji, Palestine, Russia, Samoa.
Historical corrections for Alaska and British East Africa.

On a platform that isn't supplying __FILE__, previous coding would either
crash or give a stale result for the filename string.  Not sure how likely
that is, but the original code catered for it, so let's keep doing so.

In vpath builds, the __FILE__ macro that is used in verbose error
reports contains the full absolute file name, which makes the error
messages excessively verbose.  So keep only the base name, thus
matching the behavior of non-vpath builds.

The correct information appears in the text, so just remove the statement
in the table, where it did not fit nicely anyway.  (Curiously, the correct
info has been there much longer than the erroneous table entry.)
Resolves problem noted by Daniele Varrazzo.

In HEAD and 9.1, also do a bit of wordsmithing on other text on the page.
