answering the other email in this one too:

check_PROGRAMS are the list of binaries built on 'make check'.
TESTS are the list of binaries executed on 'make check'

this is what we currently use in the server. the problem with it is that if
the checks take a while, people are less inclined to run make check.  the
result of this is that tests may have build errors until someone who
actually runs make check notices.

the reason why i chose noinst_PROGRAMS here is so that the tests 
built when running 'make', but _executed_ when running 'make check'.
this avoids the aforementioned build errors in the tests. so yes,
noinst_PROGRAMS was quite intentional here, and I'm planning to send out a
similar patch for the server.

as for the XORG_ENABLE_UNIT_TESTS, I don't mind having it there, it has no
maintainance requirement and if someone absolutely wants to disable the unit
tests, so be it. this makes more sense in a long-term approach if tests use
libraries that may not be available (such as glib) or if the tests require a
certain setup that may not be available (e.g. running X server).
