Tk Source Code

xlib/X11/X.h needs the following patch in order for it to compile on 64-bit windows, when using x64 builds of mingw-w64 ports of gcc-13 (and probably earlier versions of gcc, too).

As it stands, the "__int64" type is unknown to these mingw_w64 ports because (I think) _mingw.h has not been included.

Fixed [cf6c186a3d59ea3f|here]. Thanks for the report.

Starting with Tk 8.7/9.0, we no longer support VS < 2015, which means long long is available always. No need to use __int64 at all any more, so this is a good change anyway.
