From 3f5aa7dfa64c8757e5eef7b1bf870ec754e40f96 Mon Sep 17 00:00:00 2001 From: Cheng Sun Date: Sat, 26 Nov 2011 16:36:50 -0800 Subject: pthread: track thread existence in a separate variable. This fixes a compile error on mingw32 when using p->thread directly (as if it were a pointer) to track thread existence, because the type is opaque and may be a non-pointer. Signed-off-by: Ronald S.
