Hello!
Today I tried to build qemu from git in the current version of MSYS2 for
Windows 10 (X64).
As a result, got the file qemu-setup-4.0.50.exe
But on the way to this I met several problems that I want to share.
Sorry to be newbie and write in bad english. And so...
After resolving all packages dependencies, I execute the commands:
$ ./configure --enable-gtk --enable-sdl --enable-vnc-sasl
--enable-capstone=system --enable-docs

Problem 2: I wanted to use the --enable-vnc-sasl option, but the build stopped
due to a conflict of iovec structure definitions in files
/mingw64/x86_64-w64-mingw32/include/sasl.h and include/qemu/osdep.h
I made simple patches:
