Subject: Avoid __declspec(thread) by default, for both scratch
X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?a=commitdiff_plain;h=c53bd28a003b43d77a08bf70a3cb54001d1f4afe;p=p5sagit%2Fp5-mst-13.2.git

Avoid __declspec(thread) by default, for both scratch
return areas and THR stuff. Use struct thread intern instead.
