The same way that Cygwin implements fork (the msys2-runtime is a very light fork of Cygwin):

https://www.cygwin.com/faq.html#faq.api.fork

The packages in the msys2 repository (which, if they link to msys-2.0.dll are all GPL licensed) only really exist to aid building the packages in the mingw32 and mingw64 repositories which don't implement fork() at all and are the real purpose of MSYS2, i.e. providing normal Windows software.

If you want a POSIX-y system, please use Cygwin.

midipix has real fork. It's in alpha http://midipix.org/

midipix is a very interesting project.

what is the benefit for midipix comparing with mxe.cc mentioned above?

real fork is the benefit

Hi totally not topic related but i just created a acc just to ask you rather rudely one thing. Could you tell me how the FPS locking works in MGS Integral? I've found a post of you years back about working on the pc port. I've been hacking away the last few days. managed to make it run semi decent on W10 64b & fullscreen But the frames are locked at 24fps ingame (not 30 as you thought to remember in that post) wish you give me some pointers i have allot more questions. I'd appreciate any form of help. my mail// j j r t 1 9 9 0 AT G mail DOT com
