but this commit gets the bulk of the picayune diffs in place.

For example: some systems using older time zone libraries fail to apply
daylight-saving corrections to dates before 1970, causing
pre-1970 <acronym>PDT</acronym> times to be displayed in <acronym>PST</acronym> instead. This causes a
few differences in the <filename>horology</> regression test.
For example: some systems interpret very small floating-point values
as zero, rather than reporting an underflow error. This causes a
few differences in the <filename>float8</> regression test.
Therefore, we provide a variant comparison file,
<filename>horology-no-DST-before-1970.out</filename>, which includes
<filename>float8-small-is-zero.out</filename>, which includes
the results to be expected on these systems. To silence the bogus
<quote>failure</quote> message on <systemitem>HPUX</systemitem> platforms,
<filename>resultmap</filename> includes
<quote>failure</quote> message on <systemitem>OpenBSD</systemitem>
platforms, <filename>resultmap</filename> includes
<programlisting>
horology/.*-hpux=horology-no-DST-before-1970
float8/i.86-.*-openbsd=float8-small-is-zero
</programlisting>
which will trigger on any machine for which the output of
<command>config.guess</command> includes <literal>-hpux</literal>.
<command>config.guess</command> matches <literal>i.86-.*-openbsd</literal>.

platforms where it's appropriate.
