At a quick glance, it looks like you didn't do the locking that
apache added to make it thread-safe. Was that a conscious choice,
because msdn says these functions maintain a single 'tm' struct
per thread, at least for this version:

of the runtime? (I didn't try to find what the msvc runtime
normally used by MinGW does.)
