> 3. Include path for xpm in MSYS2+MinGW-w64 is handled in the same way
> as in Cygwin.  Perhaps, the same type of comment as was added for

Thanks.  I installed items 1, 2, and 4, but not item 3.

If you think we should do something about the xpm.h header, then
please try this alternative solution: copy the xpm.h header file into
the X11 subdirectory of your GCC 'include' directory (the one where
you have all the standard C header files), then try configuring and
building Emacs without adding the "-I/mingw64/include/noX" switch to
CPPFLAGS.  If that doesn't work, please show the error messages you
get from the compiler, and let's take it from there.

If, for some reason, you think that copying xpm.h to include/X11/xpm.h
is not appropriate, please explain why you think so.
