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