  16 dnl
  17 dnl the "ISO C9X: 7.18 Integer types <stdint.h>" section requires the
  18 dnl existence of an include file <stdint.h> that defines a set of
  19 dnl typedefs, especially uint8_t,int32_t,uintptr_t.
  20 dnl Many older installations will not provide this file, but some will
  21 dnl have the very same definitions in <inttypes.h>. In other environments
  22 dnl we can use the inet-types in <sys/types.h> which would define the
  23 dnl typedefs int8_t and u_int8_t respectivly.
  24 dnl
  25 dnl This macros will create a local "_stdint.h" or the headerfile given as
  26 dnl an argument. In many cases that file will pick the definition from a
  27 dnl "#include <stdint.h>" or "#include <inttypes.h>" statement, while
  28 dnl in other environments it will provide the set of basic 'stdint's defined:
  29 dnl int8_t,uint8_t,int16_t,uint16_t,int32_t,uint32_t,intptr_t,uintptr_t
  30 dnl int_least32_t.. int_fast32_t.. intmax_t
  31 dnl which may or may not rely on the definitions of other files.
  32 dnl
  33 dnl Sometimes the stdint.h or inttypes.h headers conflict with sys/types.h,
  34 dnl so we test the headers together with sys/types.h and always include it
  35 dnl into the generated header (to match the tests with the generated file).
  36 dnl Hopefully this is not a big annoyance.
  37 dnl
  38 dnl If your installed header files require the stdint-types you will want to
  39 dnl create an installable file mylib-int.h that all your other installable
  40 dnl header may include. So, for a library package named "mylib", just use
  41 dnl      GCC_HEADER_STDINT(mylib-int.h)
  42 dnl in configure.ac and install that header file in Makefile.am along with
  43 dnl the other headers (mylib.h).  The mylib-specific headers can simply
  44 dnl use "#include <mylib-int.h>" to obtain the stdint-types.
  45 dnl
  46 dnl Remember, if the system already had a valid <stdint.h>, the generated
  47 dnl file will include it directly. No need for fuzzy HAVE_STDINT_H things...
