By "packages installed by default", I mean the packages that get
installed if you install MinGW (with the "mingw-get-inst-20120426.exe"
installer) and accept the default options in the wizard.

Sorry, I've not found a way to get the list of installed packages
(AFAICT, the package manager currently lacks such a feature).

Yes, I have image libraries, but I wanted to try first a simple build,
to make sure that a botched library setup is not the culprit of any
build failure.

Ok, I've done the above change, and now a plain "make" ends up failing here:
