Hello,
I've found that localtime_r() is a macro in pthread-win32 simply referencing
the localtime() function. According to the MSDN localtime() works just like
the UNIX version.. each call overwrites the static struct tm storage.
Is this really thread safe?
Thanks,
Laszlo
PS: a simple call like this: localtime_r (&tt, &ttm); causes MinGW to log
"warning: value computed is not used"

Yes; it uses a thread-specific buffer on win32. So it's overwritten
with every call in that thread.
