It is 19 make re-executions. The reason non-recursive is slower is that I
haven't had a chance to optimize it yet. I actually expect it to be faster
than recursive (for obvious reasons).
OK, this makes sense.
Regarding the topic at hand, we don't use -MP, but post-process the output
and create empty targets for the header files. For example:
my_header:
That's exactly what gcc does.
I misunderstood. When you said PHONY targets, I thought you meant it generates
".PHONY: my_header" as well, not just an empty target.
