+dnl @synopsis AX_CREATE_STDINT_H [( HEADER-TO-GENERATE [, HEADERS-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.
+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...
