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

[Akim Demaille]

| I would like to suggest the following patch, which solves two
| different issues:
| 
| 1. When you change configure.ac and run make in a deep hierarchy it
|    takes hours to regenerate all the Makefiles from Makefile.ins.
| 
| 2. When there are actions that Automake doesn't know about
|    (AC_CONFIG_COMMANDS creating files), they never get a chance of
|    being run.
| 
| The idea is that we should probably run plain ./config.status at the
| top level update of Makefile.
| 
| Hm...  Of course, I can't cvs diff :(  I don't have an Internet access
| for the time being.  Here is a hand written patch:

Actually, the same should apply to running automake:
