Perhaps we should make it the default?
For iscygpty.c, how about adding `-UWINVER -DWINVER=0x0600`? (Not tested.) iscygpty requires new Win32 APIs which were added in Windows Vista. For the other problem, I think your MinGW is too old. (The above problem should be caused by the same reason, though.) I highly recommend you to use MinGW-w64 instead of the original MinGW (which looks dead). There are some distributions which provide binary packages of MinGW-w64, and I think MSYS2 is the best. (https://www.msys2.org/) If we still need to support the original MinGW, we might need some modifications to the codes and makefiles. However, I can't help it, because I have already uninstalled the original MinGW. Regards, Ken Takata -- -- You received this message from the "vim_dev" maillist. Do not top-post!
