 OK, I wrote the following functions that you can be found
 [https://github.com/zarch/grass_basename here]:

     - G_get_numb_of_decimals, return the number of decimal in a string;
     - G_double_to_str, return a formatted string substituting . with _ in
 double number;
     - G_get_basename_sep, return the basename separator using the default
 or the one find in the GRASS_BASENAME_SEP variable;
     - G_join_basename_strings, takes an array of strings and return a
 joined string using the basename separator;
     - G_get_format_name, takes a basename string and a double number and
 return a formatted string;

 I'm using ``malloc`` and ``free`` instead of ``G_malloc`` and ``G_free``
 just to make it easier to test outside GRASS

 Do you have any comments?

 Should I create a directory in trunk/lib/basename containing
 [https://github.com/zarch/grass_basename/blob/master/basename.c
 basename.c] and put the
 [https://github.com/zarch/grass_basename/blob/master/basename.h
 basename.h] in trunk/include/defs?
