	As Matus says, you'll need to add some conditionals to the scp2 stuff -
both in the makefile.mk's (or you can update SCPDEFS as generated by
configure.in), and to add #ifndef HEADLESS's around the place there :-)

	When you've done that a rm -Rf unxlngi6.pro ; build && deliver in scp2
- before re-running make install is prolly what you want to do.

	Makes good sense :-)

	Of course, I'd push to something that works, and then clean it up
later; but some thoughts:

	The Library_vcl.mk is becoming a bit of a rats-nest of cut/paste, I
wonder if we can chunk up the common files into another variable that we
can re-use in these different per-platform sections; I appreciate
everyone else just munged it but ... ;-)

	I'm surprised we need to disable lingucomponent, linguistic,
lotuswordpro, oovbaapi, vbahelper and wizards to build headless: of
course, quite probably we don't want at least some of those - but did
they really cause build issues ?

	Otherwise, it looks rather sane really :-)

	Oh - that is odd. Do you really want to create the plugadapt instance ?
or have your own headless instance (mirroring a cut down version of the
Android one perhaps ?).

	Of course, it is necessary to have the vcl/headless/ stuff connected up
somewhere, we'll still  need SalFrames in order to post events, and some
sort of event loop to run the app, but it shouldn't be hard to get a
really simple bitmap-rendering version in there.

	All the best,

		Michael.
