I'm sure that patches to support cross-compilation will be very
welcome, thanks in advance.  This would require some modifications to
the configure script, I think, because it currently doesn't seem to
DTRT for a MinGW build.

this is ridiculous.

It is nowhere hard to support cross compiler tbh.

How so?  io.h is a standard header in MinGW, how did it happen that
you don't have it?

This file isn't supposed to be compiled into the MinGW port of GNU
Make.

I suspect that you use the Posix configure script to build the port.
That is not supported.  You should use the build_w32.bat batch file
(which means you cannot cross-compile, only build it natively on
MS-Windows).

This is completely wrong tbh.
