See thread starting with article 368516 in komintern. Since our upgrade to gcc 4.5, win32 binaries are broken, unless one explicitly links libstdc++ statically. These bugs seems at least somewhat relevant: http://sourceforge.net/tracker/index.php?func=detail&aid=3003520&group_id=2435&atid=102435 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=317146 https://bugzilla.redhat.com/show_bug.cgi?id=489100 Note that simply deleting libstdc++-6.dll fixes the problem.

Right now we're linking this static anyway, but let's keep track of this is we want to change that approach in the future.
