Mach cthreads support based on:
Subject: perl5.005_02 patch for mthreads
To: perl5-porters@perl.org
Message-ID: <MLIST_Pine.GSO.4.04.9810231410220.11111-200000@sulaco.eos.home.net>
Pthread yield probe (dejavu)
Cosmetic nanochange for the union semun output.
Better inttypes.h probe.
Undo the 'void *' $selecttype probe from #1971 because
it breaks the $selectminbits test.
