Benoît Minisini 4c02c6d338 ******** Merged /branches/64bits r918:1003 into /trunk
[CONFIGURATION]
* NEW: 64 bits port.

[EXAMPLES]
* BUG: Fixed the AnalogWatch example.

[WIKI CGI SCRIPT]
* NEW: Some little cosmetic changes.

[INTERPRETER]
* NEW: The extern function implementation has been redesigned and is now
  based on libffi, so that it works on 64 bits system. Because of a flaw in
  the compiler design, projects that use the Pointer datatype must be
  recompiled to be used on a 64 bits system. This flaw will be fixed in
  Gambas 3.
* OPT: Put some tables into read-only memory. About 1000 bytes are saved
  for each running interpreter, except the first one.
* BUG: Does not crash anymore if a component cannot be loaded.
* NEW: Spanish translation updated.
* NEW: A new interpreter API for returning a pointer.

[COMPILER]
* BUG: Correctly compiles LONG constants inside code.

[GB.DEBUG]
* BUG: Compiles and links the gb.debug components with the thread
  libraries.

[GB.DB.SQLITE3]
* BUG: Getting the primary index of a table without primary index is safe
  now.

[GB.GTK]
* BUG: Modified the GLib priority of watched descriptors, as the main loop 
  could enter in a loop in which user interface events were not managed.
* BUG: Message boxes use application title without crashing now.

[GB.OPENGL]
* BUG: Disable dead code.

[GB.QT.EXT]
* BUG: TextEdit.TextWidth and TextEdit.TextHeight were not declared as
  read-only properties.

[GB.XML.XSLT]
* BUG: XSLT class is now declared as being not creatable.
