Comment (by ryandesign):

 Upstream has fixed it by including that header so we could add a patch to
 MacPorts to do the same.

 However it's also pointed out in the upstream issue that this code only
 takes effect when xinput was found and is only relevant to X11, and while
 we do offer xinput and X11 in MacPorts, this port does not declare
 dependencies on xinput or any other X11 ports, so this use may be
 unintentional. For example if I configure dosbox-staging on my system
 using trace mode (on Monterey where it works; [ticket:66358 trace mode is
 broken on Ventura] and later), I see:

 {{{
 --->  Configuring dosbox-staging
 Warning: The following existing files were hidden from the build system by
 trace mode:
   /opt
   /opt/local/bin/ar
   /opt/local/bin/git
   /opt/local/bin/gmake
   /opt/local/bin/lipo
   /opt/local/lib/pkgconfig/xi.pc
   /private/var/select/sh
   /usr/X11R6
 }}}

 And:

 {{{
 % port provides /opt/local/lib/pkgconfig/xi.pc
 /opt/local/lib/pkgconfig/xi.pc is provided by: xorg-libXi
 }}}

 xorg-libXi is the X11 input extension.

 So the port should either declare a dependency on xorg-libXi if it wants
 to use it, or ensure that it will not be used even if it is installed.
