Sergey,
Thanks for the update. I've been meaning to reply by the email slipped
through the cracks! I'm glad you figured it out. As you found out,
different gcc versions behave differently, that is why we have ifdefs that
checks for gcc version in a few places including the one you pointed out.
MinGW/64/MSYS are what I have been using for a long time. Interestingly
enough, Windows 10 is bringing bash/Ubuntu-subsystem support in the near
future, which is something I will definitely try and test with Unicon.
Thanks again!,
Jafar
