The makefiles still need some work (DLL names are wrong), but please feel free to pick the 3 first commits in the meantime.

Fixed up DLL names. irpmonc builds and starts up without errors.

[tormodvolden]

Actually it seems the previous DLL names (for the C source code libraries) were fine, but they are only wrappers, and the missing libraries on start-up are DLL's built from Pascal sources. It becomes a bit more work than I originally planned for. I was hoping irpmonc didn't require building Pascal code.

Just bookmarking in case I come back to this:

It would be nice to have the 3 first commits merged/picked because then I can leave the makefiles uncommitted in my tree while working and compiling on other branches.

You can do:
git fetch https://github.com/tormodvolden/IRPMon.git mingw
git merge FETCH_HEAD^
