When specifying the path to the MinGW Makefile on the make command line, use
a relative path specification. For example:

<verbatim>
$ make -f
</verbatim>

This is because the Makeheaders program has a problem with full paths on Windows:

<verbatim>
$ makeheaders
Can't read input file "d"
</verbatim>

I think this is because the colon is used on Windows as a device name separator.
