Something relevant to your project. For example, gnulib uses gl_,
coreutils uses cu_, libtool uses lt_, m4 uses M4_. It doesn't have to
be limited to 2 alphabetics; but it should be your own prefix rather
than stomping on ac_ (autoconf) or am_ (automake), so that your package
isn't hurt if the autotools later make use of that variable name in a
different way.
