   8  * This section typedefs the old 'native' types to the new <stdint.h> types.
   9  * These redefinitions are provided solely to allow JSAPI users to more easily
  10  * transition to <stdint.h> types.  They are not to be used in the JSAPI, and
  11  * new JSAPI user code should not use them.  This mapping file may eventually
  12  * be removed from SpiderMonkey, so don't depend on it in the long run.

  16  * BEWARE: Comity with other implementers of these types is not guaranteed.
  17  *         Indeed, if you use this header and third-party code defining these
  18  *         types, *expect* to encounter either compile errors or link errors,
  19  *         depending how these types are used and on the order of inclusion.
  20  *         It is safest to use only the JSAPI <stdint.h>-style types,
  21  *         customizing those types using MOZ_CUSTOM_STDINT_H if necessary.
