dnl ----- maintainer mode
dnl  + enables "maintainer mode" only with ./configure --enable-maintainer-mode
dnl    - causes make __never__ to invoke 'config/missing' (i.e. any autotools)
dnl    - basically a hack to avoid version mismatches in autoconf, automake, etc.
dnl      for autobuilds from SVN
dnl  + maintainer should call ./configure --enable-maintainer-mode, and must keep
