Very much agreed. We can still make it for 2.50. Must be run by
default, of course.

AS_, I would say. Unless we plan to move it the day AS_ will need it,
I don't think today it does. But it will probably happen some day.

This one is quite common. Not very Autoconf like, but I'm not sure we
should try something else. Maybe we can make a small executable in
pwd, set PATH to '.:`pwd`', and try `.;`pwd`' and keep the one that
works? Maybe *starting* with `;' would address the issues you mention
at the end (Cygwin accepting too easily `:').

A bit big, but I'm fine with it.
