Looks like good work.

This is possibly not needed.

You should be able to use NULL instead of the hinst when creating the 
window, which would eliminate the need for g_hinst.

Maybe it would be nicer to check hWndDateTime with an ok() macro in 
test_datetime_control() then use skip() if it's NULL.  This way the test 
will fail without crashing in the case that Window creation fails, for 
example, when there's no X display available.  When tests crash, make 
doesn't detect that they failed.

The return is redundant, and probably better off removed.

MSDN does say "returns nonzero if successful", but it's probably better 
to check the exact value that it does return, in case there's a program 
out there that does the same. ie.

ok(r == 1, "Expected nonzero, got %ld\n", r);
