M-x flymake and (add-hook 'c-mode-hook 'flymake-mode) are the two most
mundane ways I can think of for starting flymake.

I've dug a little more and it happens when the visited file is in a
project without a dominating file called "Makefile". So I wrote

But only the second part is true. But it's still pretty common. Notice
for example, how that includes visiting files in a clean Emacs checkout
before the configure step.

Good question! I guess few people are using it, or they're using it
with special care, or they are used to the _flymake.c garbage
anyway because the old flymake used to make it from time to time (though
not in such a trivial case)
