Subject: Fix pre-Vista compatibility.
X-Git-Tag: v2.9~2
X-Git-Url: http://git.iain.cx/?p=nssm.git;a=commitdiff_plain;h=3405b53f659462281af9f839062b9322d2093277

Fix pre-Vista compatibility.

SleepConditionVariableCS() isn't available on Windows versions
prior to Vista.  Use a waitable timer instead.
