Hi there, I think there is a tiny typo in the documentation at https://www.gnu.org/software/make/manual/html_node/Special-Targets.html#Special-Targets under the *.secondary* name it says:
Of course, of one of the source files *were* updated... I believe it should be Of course, *if* one of the source files *were* updated... so just changing the second `of` to be `if`. Thank you! -- Andrey Melnikov
