[tor-commits] [tor/master] Use the standard _WIN32, not the Torism MS_WINDOWS or deprecated WIN32

31 Jan 2012

commit 5cf9167f919dfef964b1d149731ed04941e25ebf
Author: Nick Mathewson nickm@torproject.org
Date:   Tue Jan 31 10:59:42 2012 -0500
Use the standard _WIN32, not the Torism MS_WINDOWS or deprecated WIN32
This commit is completely mechanical; I used this perl script to make it:
#!/usr/bin/perl -w -i.bak -p
if (/^\s*#/) {
         s/MS_WINDOWS/_WIN32/g;
         s/\bWIN32\b/_WIN32/g;
     }
