This is obliquely stated in the documentation:
`.SECONDARY'
The targets which `.SECONDARY' depends on are treated as
intermediate files, except that they are never automatically
deleted. *Note Chains of Implicit Rules: Chained Rules.
`.SECONDARY' with no prerequisites marks all file targets mentioned
^^^^^^^^^^^^^^^^^^^^^^^^^^
in the makefile as secondary.
^^^^^^^^^^^^^^^
Note the second paragraph. The targets you give aren't mentioned in the
makefile; they're built using implicit rules.
I agree with you, however, that this is a strange restriction and this
area needs to be revisited, for all of PRECIOUS, INTERMEDIATE, and
SECONDARY.
I'll file an enhancement request about it.
