#defines the list of preprocessor macros below. The config.h file can pre-define any of these to short-cut the definitions. This is usually only necessary if the preprocessor does all of its math using integers.

Sizes of built-in types:

- ACE_SIZEOF_CHAR
- ACE_SIZEOF_WCHAR
- ACE_SIZEOF_SHORT
- ACE_SIZEOF_INT
- ACE_SIZEOF_LONG
- ACE_SIZEOF_LONG_LONG
- ACE_SIZEOF_VOID_P
- ACE_SIZEOF_FLOAT
- ACE_SIZEOF_DOUBLE
- ACE_SIZEOF_LONG_DOUBLE

Wrappers for built-in types of specific sizes:

- ACE_USHORT16 (For backward compatibility. Use ACE_UINT16 instead.)
- ACE_INT8
- ACE_UINT8
- ACE_INT16
- ACE_UINT16
- ACE_INT32
- ACE_UINT32
- ACE_UINT64 (
  Note:
    ACE_INT64 is partly defined, there is no ACE_LongLong for platforms that don't have a native 8-byte integer type.)
  Byte-order (endian-ness) determination: ACE_BYTE_ORDER, to either ACE_BIG_ENDIAN or ACE_LITTLE_ENDIAN
