Benoît Minisini 89d42c3d40 [INTERPRETER] 
* NEW: Add a new API to create an object without calling the constructors.

[GB.CRYPT]
* BUG: Fix bad casting of strcmp() return value to boolean. The same 
  security flaw has been found in MySQL recently. See 
  http://seclists.org/oss-sec/2012/q2/493

[GB.GTK]
* BUG: Fix bad casting of strcmp() return value to boolean in the Font 
  management.

[GB.GSL]
* NEW: Matrix class built the same way as the Vector class, i.e. with the 
  ability to switch transparently between Float or Complex elements.
