CC65 patches for Apple1/Replica1

The Apple1 is a questionable target for a C compiler due to its small memory size and disjointed memory map. The Replica1, on the other hand, is a near perfect single board target with its 32K contiguous RAM and nice I/O expansion. Compare this with what WDC offers as a single board development platform for $695.
