[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. git-svn-id: svn://localhost/gambas/trunk@1006 867c0c6c-44f3-4631-809d-bfa615b0a4ec
