* BUG: Do not compile database manager anymore, it has been deprecated. * BUG: Compile the gb.dbus component. [INTERPRETER] * NEW: Pointer is a real datatype now. * NEW: Static arrays came back. They are now like real array classes, except that they are not resizable. * NEW: IsPointer() is a new function that tells if an expression is a pointer. * NEW: All XXXX?() function synonymous were removed. Use the IsXXXX() version instead. * NEW: Remove now useless source files. [COMPILER] * NEW: Static arrays came back, with actually the same syntax as before. [EXAMPLES] * BUG: Fix the examples according to the new array syntax. git-svn-id: svn://localhost/gambas/trunk@2949 867c0c6c-44f3-4631-809d-bfa615b0a4ec
