Ok, sensible. Yes, a lot of other packages make bad examples :(
Let's hope for them to be still alive and updated when automake 1.14
is out - it will remove and flag out some terribly old remnants.

Surely, just that:
AM_INIT_AUTOMAKE([foreign])

Indeed.

I find that program quite useless..

You could do that, though I would simply direct users to read the compiler
error message. That enhances (hopefully) both their knowledge on compiling,
and reduces the walltime configure runs.

If I understood right, kconfig-frontends is supposed to run on non-Linux too,
and I have yet to see a modern platform that's missing any of the stdc
functions like malloc and strchr.
