I don't have such dependencies. If I manually change the path in the
generated Makefile, I can compile and link and everything works
perfectly.

I know of the DevKit (and use it, too). The reasons are more for
convenience purposes: For the deployment of the extension as a gem, the
DevKit will be our way to go, but for the integration in our build
process (using CMake), during which we use the extension, it would be
easier to use the extension directly (without a gem). So I tried to
implement it that way, and the only obstacle I had, does IMO base on an
obvious misconception in the mkmf code: MinGW implies MSYS; although
this is the normal case under windows due to the DevKit.

I made a proposal to use the OS_TYPE environment variable, but I don't
know if this will work on all systems. If no one can tell if this would
work and no one else is interested in fixing this and supporting the
MinGW-only use case, I must try to integrate the DevKit in our build
environment. In this case: Would it be possible to integrate DevKit's
MinGW+MSYS environment without the involvement of RubyGems.

Kind regards
Marcel
