The checked api test would, I think, be useful only if either
1) it would give a different answer on Win64
or
2) it takes a large amount of time and would be faster on Win64.
Unless it would give a different answer, it would not be useful to
*add* it, as you'd just get the same answer twice.
It appears to take about 1 minute and 10 seconds, if I'm reading
http://buildbot.wireshark.org/trunk/waterfall
correctly; the entire build takes about an hour and a half, so I don't
think the speed of the checked api tests is an issue.
I also don't know of any reason why it'd give a different answer on
Win64, as it's just a Perl script scanning source code - it should
give the same answer on all platforms, modulo places where it depends
(probably unintentionally) on behavior specific to particular versions
of the Perl interpreter or Perl packages.
