It was added when the toplevel Cygnus configure script was converted to an Autoconf configure.in; so it was actually the first time that Autoconf was really used to detect tools for Canadian crosses: previously, the toplevel configure detected it and passed it directly to the subdirectories (gcc, binutils, bfd, etc.). Maybe we are still in time to add a deprecation warning like that for shell functions? Paolo
