warn-on-use: work with old autoconf Before autoconf documented the AS_VAR_* interfaces, it used to require the user to pre-expand the pushed macro name. Newer autoconf can see through macros, but this is one case where breaking the rule of thumb and underquoting does not hurt. * m4/warn-on-use.m4 (gl_WARN_ON_USE_PREPARE): Accomodate older AS_VAR semantics of autoconf 2.60.
