No problem at all, I sometimes take months to reply.

Yeah, it operates only on those makefiles which have also been listed as
command line arguments to config.status.

It merely ensures that all files included by the makefiles exist; if one
doesn't exist yet, then it creates a dummy file.

The most helpful is when you also have time stamp information from
*before* running that 'make' which doesn't rebuild.  I know it sounds
almost impossible to get reliably, but that's what usually leads
straight to the answer.
