/**
* USE_PROTOTYPES: Use full ANSI prototypes.

* CLOCK_PRIMS: We want the timer/clock prims to be used
*
* LITTLE_ENDIAN: This is for the intel machines or other
* little endian processors. Defaults to big endian.
*
* NO_LVALUE_CASTING: This is for compilers that don't like the left side
* of assigns to be cast. It hacks around to do the
* right thing.
*
* ATOMIC_FLOAT_ACCESS: So that float operations will work.
*
* LINKED_USER_PRIMITIVES: Indicates that user primitives are statically linked
* with the VM executeable.
*
* OLD_SPACE_SIZE_DIFF: The 68k uses a different amount of old space.
* This "legitimizes" the change.
*
* SIMPLE_SIGNAL: For machines that don't use real signals in C.
* (eg: PC, 68k)
*
* OS_NAME_LOOKUP: Use nlist to lookup user primitive addresses.
*
* VMCALL: Tag for all functions called by the VM.
*
* VMAPICALL: Tag for all functions called via the PlatformFunction
* callWith: mechanism.
*
* SYS_FLOAT: For some math functions where extended types (80 or 96 bits) are returned
* Most platforms return as a double
*
* FLOAT_EXTENDED: If defined, the type name for extended precision floats.
*
* PLATFORM_IS_ASCII: Must be defined if the platform is ASCII
*
* EXE_EXTENSION_CHAR: the executable has a delimiter that we want to stop at as part of argv[0].
