Indeed :)

Currently -Wno-portability is the default in --foreign mode
while -Wportability is the default for --gnu and --gnits.

I'm fine with defaulting to -Wno-portability in all cases, to
help the 1.6-1.7 transition (since -Wno-portability is not
supported by 1.6).

I'd vote for this.  I expect Automake to help rookie Makefile.am
authors writing portable Makefiles.  Veterans that *know* what
they do can tell Automake they play a different game.  I don't
think the converse is reasonable (clueless people asking for
extra help).

 Ralf> May-be having a --pedanic mode instead would be better.

I guess that'd be pretty much the same as `-Wall' or `-Wall -Werror'.
