* BUG: Fixed the allocation of static arrays. * BUG: Array classes array accessors now correctly check the number of their argument when the array has just one dimension. * OPT: Native array classes array accessors were optimized. For one dimension arrays, reading is about 50% faster and writing 25% faster. The gain is smaller for higher dimensions. git-svn-id: svn://localhost/gambas/trunk@1035 867c0c6c-44f3-4631-809d-bfa615b0a4ec
