I have 3.81, and that's the only version for which I can find online
documentation.

Can you check the 3.80 documentation to ensure that order-only
prerequisites are mentioned? They should be described in:

	4 Writing Rules
	4.3 Types of Prerequisites

Other than that, I can only suggest re-building a directory with make
debugging enabled (make -d ...). It can generate a lot of output, so
pick the smallest case which demonstrates the problem (e.g. a module
with only one source file).
