flymake-log is a compiled Lisp function in `flymake.el
'.
(flymake-log LEVEL TEXT &rest ARGS)
Log a message at level LEVEL.

ignored. Otherwise, it is printed using `message'.
TEXT is a format control string, and the remaining arguments ARGS
are the string substitutions (see the function `format').
