Re: Running a plain ./config.status at top level

Ah, OK, thanks for the explanation!

Well, I updated my patch to make it dynamic: now, on my source tree,
if I

   touch Makefile.am
   => automake Makefile
   => ./config.status Makefile

and if I

   touch configure.ac
   => automake
   => ./config.status

make check is running.
