dnl Taken from ac-archive ac-archive-5 module's CVS HEAD

dnl ac-archive is available at http://ac-archive.sf.net

dnl URL of WebCVS of this m4 macros is:

dnl @synopsis AX_CREATE_STDINT_H [( HEADER-TO-GENERATE [, HEDERS-TO-CHECK])]
7 
dnl
8 
dnl the "ISO C9X: 7.18 Integer types <stdint.h>" section requires the
9 
dnl existence of an include file <stdint.h> that defines a set of
10 
dnl typedefs, especially uint8_t,int32_t,uintptr_t. Many older
11 
dnl installations will not provide this file, but some will have the
12 
dnl very same definitions in <inttypes.h>. In other enviroments we can
13 
dnl use the inet-types in <sys/types.h> which would define the typedefs
14 
dnl int8_t and u_int8_t respectivly.
15 
dnl
16 
dnl This macros will create a local "_stdint.h" or the headerfile given
17 
dnl as an argument. In many cases that file will just "#include
18 
dnl <stdint.h>" or "#include <inttypes.h>", while in other environments
19 
dnl it will provide the set of basic 'stdint's definitions/typedefs:
20 
dnl
21 
dnl   int8_t,uint8_t,int16_t,uint16_t,int32_t,uint32_t,intptr_t,uintptr_t
22 
dnl   int_least32_t.. int_fast32_t.. intmax_t
23 
dnl
24 
dnl which may or may not rely on the definitions of other files, or
25 
dnl using the AC_CHECK_SIZEOF macro to determine the actual sizeof each
26 
dnl type.
27 
dnl
28 
dnl if your header files require the stdint-types you will want to
29 
dnl create an installable file mylib-int.h that all your other
30 
dnl installable header may include. So if you have a library package
31 
dnl named "mylib", just use
32 
dnl
33 
dnl      AX_CREATE_STDINT_H(mylib-int.h)
34 
dnl
35 
dnl in configure.ac and go to install that very header file in
36 
dnl Makefile.am along with the other headers (mylib.h) - and the
37 
dnl mylib-specific headers can simply use "#include <mylib-int.h>" to
38 
dnl obtain the stdint-types.
39 
dnl
40 
dnl Remember, if the system already had a valid <stdint.h>, the
41 
dnl generated file will include it directly. No need for fuzzy
42 
dnl HAVE_STDINT_H things...
