dnl @synopsis AX_CREATE_STDINT_H [( HEADER-TO-GENERATE [, HEDERS-TO-CHECK])]
dnl
dnl the "ISO C9X: 7.18 Integer types <stdint.h>" section requires the
dnl existence of an include file <stdint.h> that defines a set of
dnl typedefs, especially uint8_t,int32_t,uintptr_t. Many older
dnl installations will not provide this file, but some will have the
dnl very same definitions in <inttypes.h>. In other enviroments we can
dnl use the inet-types in <sys/types.h> which would define the typedefs
dnl int8_t and u_int8_t respectivly.
dnl
dnl This macros will create a local "_stdint.h" or the headerfile given
dnl as an argument. In many cases that file will just "#include
dnl <stdint.h>" or "#include <inttypes.h>", while in other environments
dnl it will provide the set of basic 'stdint's definitions/typedefs:
dnl
dnl   int8_t,uint8_t,int16_t,uint16_t,int32_t,uint32_t,intptr_t,uintptr_t
dnl   int_least32_t.. int_fast32_t.. intmax_t
dnl
dnl which may or may not rely on the definitions of other files, or
dnl using the AC_CHECK_SIZEOF macro to determine the actual sizeof each
dnl type.
dnl
dnl if your header files require the stdint-types you will want to
dnl create an installable file mylib-int.h that all your other
dnl installable header may include. So if you have a library package
dnl named "mylib", just use
dnl
dnl      AX_CREATE_STDINT_H(mylib-int.h)
dnl
dnl in configure.ac and go to install that very header file in
dnl Makefile.am along with the other headers (mylib.h) - and the
dnl mylib-specific headers can simply use "#include <mylib-int.h>" to
dnl obtain the stdint-types.
dnl
dnl Remember, if the system already had a valid <stdint.h>, the
dnl generated file will include it directly. No need for fuzzy
dnl HAVE_STDINT_H things...
