Hi there,

GCC developers that also track the Parma Polyhedra Library (PPL, 
http://www.cs.unipr.it/ppl/)
are in a situation whereby, while the GCC compiler is requiring Autoconf 
version 2.59 (precisely
that one), the PPL requires a version >= 2.61.  This is annoying, because they 
are forced to
use at least two different versions of Autoconf.

Basile Starynkevitch (in CC) suggested we put a generated configure script on 
the CVS
repository.  Thus we now have configure.repo in the repository, the idea being 
that
a simple

    mv configure.repo configure

could be used as an alternative to autoconf.  However, the problem remains how
to perform the update of all the other generated configuration files.
In other words, we would need something that acts like autoreconf except
for the fact that it would not attempt to build configure from configure.ac.
Probably a small shell script invoking libtool, aclocal, automake
in the right order and recursing to subdirectories is what is needed, but
we are not sure.   What is the right solution?
All the best,

   Roberto
