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.B�KCB��؛[H�\ܝΈ����Y��[����K��؛[\˚[B��TN�����Y��[����K٘\K�B���[Y[�][ێ�����Y��[����K���˚[B�[��X��ܚX�H[��Έ����Y��[����K�[��[��X��ܚX�K\�[\CB�B
