Your conclusion is correct: The compile actions for dllobject and
libobject are not yet defined for the gcc tool.  Please try the patch
below that adds these actions.  It differs from your solution in that
the dllobject is created with an extra flag: -fPIC.  And there are no
changes to the build action, I don't see why these would be required.
Building is possible with a mix of filetypes anyway.

Best is to find situations where something goes wrong.  It's a bit
difficult to guess when libtool interferes with selecting gcc.

Your contributions are very much welcome.  I have tried to make a good
first version of Aap, but for a tool like this the experience of many
people is required to further improve it.
