Thanks for your contribution to emc. I don't have a machine with a VFD,
but I know a lot of people do.

In the medium term, we're trying to make it possible for all types of
components to be built separately from emc2. Right now there are a
number of problems that make this not work very well for userspace
components. I hope that a number of improvements in this area will be
in 2.4, but that's still a ways off.
I've prepared a tar that contains your source plus a Makefile and a copy
of the modbus source and header from emc. It should work on emc 2.3
(and maybe 2.2) systems with the emc2-dev package installed.
http://emergent.unpy.net/files/sandbox/vfs1_vfd.tar.gz
you can "make" or "make install" ("sudo make install" on systems where
emc is installed as a package)
Some of the stuff in that Makefile is far from guessable and that's why
I hope to improve this for emc 2.4.
