/*
This header defines macros with information about the C ABI.
Only information that can be determined using the preprocessor at
compilation time is available.  No try-compile results may be added
here.  Instead we memorize results on platforms of interest.

An includer may optionally define the following macros to suppress errors:

  KWIML_ABI_NO_VERIFY          = skip verification declarations
  KWIML_ABI_NO_ERROR_CHAR_SIGN = signedness of 'char' may be unknown
  KWIML_ABI_NO_ERROR_LONG_LONG = existence of 'long long' may be unknown
  KWIML_ABI_NO_ERROR_ENDIAN    = byte order of CPU may be unknown

An includer may test the following macros after inclusion:

  KWIML_ABI_VERSION           = interface version number # of this header

  KWIML_ABI_SIZEOF_DATA_PTR   = sizeof(void*)
  KWIML_ABI_SIZEOF_CODE_PTR   = sizeof(void(*)(void))
  KWIML_ABI_SIZEOF_FLOAT      = sizeof(float)
  KWIML_ABI_SIZEOF_DOUBLE     = sizeof(double)
  KWIML_ABI_SIZEOF_CHAR       = sizeof(char)
  KWIML_ABI_SIZEOF_SHORT      = sizeof(short)
  KWIML_ABI_SIZEOF_INT        = sizeof(int)
  KWIML_ABI_SIZEOF_LONG       = sizeof(long)

  KWIML_ABI_SIZEOF_LONG_LONG  = sizeof(long long) or 0 if not a type
    Undefined if existence is unknown and error suppression macro
    KWIML_ABI_NO_ERROR_LONG_LONG was defined.

  KWIML_ABI_SIZEOF___INT64    = 8 if '__int64' exists or 0 if not
    Undefined if existence is unknown.

  KWIML_ABI___INT64_IS_LONG   = 1 if '__int64' is 'long' (same type)
    Undefined otherwise.
  KWIML_ABI___INT64_IS_LONG_LONG = 1 if '__int64' is 'long long' (same type)
    Undefined otherwise.
  KWIML_ABI___INT64_IS_UNIQUE = 1 if '__int64' is a distinct type
    Undefined otherwise.

  KWIML_ABI_CHAR_IS_UNSIGNED  = 1 if 'char' is unsigned, else undefined
  KWIML_ABI_CHAR_IS_SIGNED    = 1 if 'char' is signed, else undefined
    One of these is defined unless signedness of 'char' is unknown and
    error suppression macro KWIML_ABI_NO_ERROR_CHAR_SIGN was defined.

  KWIML_ABI_ENDIAN_ID_BIG    = id for big-endian (always defined)
  KWIML_ABI_ENDIAN_ID_LITTLE = id for little-endian (always defined)
  KWIML_ABI_ENDIAN_ID        = id of byte order of target CPU
    Defined to KWIML_ABI_ENDIAN_ID_BIG or KWIML_ABI_ENDIAN_ID_LITTLE
    unless byte order is unknown and error suppression macro
    KWIML_ABI_NO_ERROR_ENDIAN was defined.

We verify most results using dummy "extern" declarations that are
invalid if the macros are wrong.  Verification is disabled if
suppression macro KWIML_ABI_NO_VERIFY was defined.
