Since you need a "td.h" file, this should be either:

file dev/testdata.c		td needs-flag
	(if you want a flag in td.h if there are any TD devices)

file dev/testdata.c		td needs-count
	(if you want td.h to define NTD equal to the number of TD
	 devices defined in the config file)

....

td.h should be created automatically by config if you use "needs-flag"
or "needs-count" in the files file.
