I'll take a stab at it. Got a few questions, tho: a) Can I assume the stack always extends into larger-addressed memory, or must I handle both cases?
b) What's the largest alignment guaranteed for pointers? Byte-level? c) Where should this code go, such that it can be replaced for the OS/platforms which need it differently? resources.c? <platform>.c? Maybe in resources.c with each <platform>.c calling the generic one in resources.c (since win32, generic, darwin, etc are all likely to share the same logic.)
