Thanks.  I thought the error was related to MinGW because
the project builds well in five or so other test
environments in both Linux and Windows.

I have solved the error by supplying the path to the missing
macros to `aclocal', and pushed that fix to the project
source.  The following `autogen.sh' works:

   aclocal -I m4
   automake --include-deps --add-missing --copy

I have forwarded your comments to the maintainers.  It is,
indeed, wrong to consider a missing required macro as a
