[Rcpp-devel] V8 crashes on 32bit windows when built with new Rtools

[JJ Allaire]

It's not posix per-se, it's "posix threads" (of which there is a win32
port available in mingw). This is done sometimes to ease porting of
software from posix to windows.

An update: Kevin submitted a patch to use win32 threads for Rtools
(restoring the previous behavior) and Duncan is rebuilding Rtools now
with this change. Once we have this update in hand we can test again.
