I'm waiting for an approval for this patch for one reason: there are
places where Automake used to proceed when it could not read a file,
and fail at exit. With this patch, it die immediately.
I did this because it is much simpler, and eases the maintenance. But
I agree that it is making automake slightly more painful. The whole
question is the tradeoff between ease of maintainability and features.
I felt the balance was in favor of maintainability, but if people
object, I'm fine with fixing this patch at the appropriate places
(i.e., just removing the corresponding chunks).
The use of General.pm will, imho, considerably ease our tasks, as it
aims at staying sync between Autoconf and Automake. I only removed
uniq currently, but I'm sure yet other things can be simplified take
more advantage of it. Conversely, I'm expecting the day Automake will
put into General.pm something that Autoconf will use :)
I suggest that Autoconf remain the original copy, AFAIK, people having
write access to Automake have it for Autoconf too.
Index: ChangeLog
from Akim Demaille <address@hidden>
* lib/Automake/Struct.pm: Update from Autoconf.
* lib/Automake/General.pm, lib/Automake/XFile.pm: New, from CVS
Autoconf.
* automake.in: Use them.
(&uniq, $me): Remove, as they are provided by Automake::General.
