Message:

o Ported GLIBC argp and getopt (argp requires the GLIBC one).

This means no optreset anylonger.

o Some corrections / hacks in the weak_alias departement.

     90   The LONG_OPTIONS argument to getopt_long or getopt_long_only is a vector

     92   zero.

     100   to the value given in the field `val' when the option is found, but
     101   left unchanged if the option is not found.
     102
     103   To have a long-named option do something other than set an `int' to
     104   a compiled-in constant, such as set a value from `optarg', set the
     105   option's `flag' field to zero and its `val' field to a nonzero
     106   value (the equivalent single-letter option character, if there is
     107   one).  For long options that have a zero `flag' field, `getopt'
