Yes, that's generally agreed.

On the other hand we want to keep backward compatibile with any
gmp version from gmp-4.3.2 to gmp-6.0.0a.

Our request to you guys would be (in case you are eventually releasing
a new gmp version):

a) Please do not over-react if flex is not working, after all this is a
released tar-ball, the flex / bison files are included as precompiled .c files,
so even the demo does compile as it is, if anybody cares.
It would be enough to remove the "exit" from the configure script IMHO.
Complaining about that badness would be OK of course.

b) Updating to a newer AutoMake version, would be nice too.


That is of course only my personal opinion, and there is no pressure
on you at all.


Thanks
Bernd.
