Here's the patch that implements a configure option to "assume the best"
instead of "assume the worst". I've called it 'risky', so people know that
it's risky to enable it.
I've put it into gnulib-common.m4, although a couple of macros in Autoconf's
functions.m4 could also profit from it. The reason is that an Autoconf
release is likely not going to happen soon.
It handles all your 120 variables, and more.
