The new FXMappedFile and FXMappedMemory classes were not finished yet,
but I thought at least they were compiling.  Perhaps its a static vs
DLL thing: as DLL, we can't have unresolved references, even if they're
not used by any code.  In static, its only unresolved if its referenced.

At any rate, I hope to do some work on them soon.
