Yes, you're right. It's autoconf test and it perfectly passed at 64-bit MinGW and 64-bit Cygwin, but not on 32-bit Cygwin.
And I don't understand why you're say that it is related to stdcall, while wglCreateContext exposed directly without any @0 @4 etc. With --enable-stdcall-fixup ld says: undefined reference to `wglCreateContext@0'
Yes, I need to use Win32.
I want to port application that heavily POSIX-dependent, but also want to save performance as much as possible.
I think if w32api-runtime package is provided it supposed to work.
