Not really.

What I had in mind was an arrangement more like

    $ for variant in linux macos; do grep include fsm-ipc-$variant.c; done
    #include "fsm-ipc-common-unix.cinclude"
    #include "fsm-ipc-common-unix.cinclude"

and COMPAT_OBJS knowning only about fsm-ipc-linux.o or
fsm-ipc-macos.o, depending on which platform you are building.
