[RFC] I suggest to add -Wall to autoconf and autoheader calls

[Felix Zielcke]

With my configure.ac autoconf[0] topic I just got the idea to add
`-Wall' option to `autoconf' in `autogen.sh'

We're using -Wall for gcc so why not for autoconf and autoheader too?

Then once in a while someone will hopefully notice that something might
need a change and will look into it.
