# SYNOPSIS

#

#   AX_CREATE_STDINT_H [( HEADER-TO-GENERATE [, HEDERS-TO-CHECK])]

#

# DESCRIPTION

#

#   the "ISO C9X: 7.18 Integer types <stdint.h>" section requires the

#   existence of an include file <stdint.h> that defines a set of

#   typedefs, especially uint8_t,int32_t,uintptr_t. Many older

#   installations will not provide this file, but some will have the

#   very same definitions in <inttypes.h>. In other enviroments we can

#   use the inet-types in <sys/types.h> which would define the typedefs

#   int8_t and u_int8_t respectivly.

#

#   This macros will create a local "_stdint.h" or the headerfile given

#   as an argument. In many cases that file will just "#include

#   <stdint.h>" or "#include <inttypes.h>", while in other environments

#   it will provide the set of basic 'stdint's definitions/typedefs:

#

#     int8_t,uint8_t,int16_t,uint16_t,int32_t,uint32_t,intptr_t,uintptr_t

#     int_least32_t.. int_fast32_t.. intmax_t

#

#   which may or may not rely on the definitions of other files, or

#   using the AC_CHECK_SIZEOF macro to determine the actual sizeof each

#   type.

#

#   if your header files require the stdint-types you will want to

#   create an installable file mylib-int.h that all your other

#   installable header may include. So if you have a library package

#   named "mylib", just use

#

#        AX_CREATE_STDINT_H(mylib-int.h)

#

#   in configure.ac and go to install that very header file in

#   Makefile.am along with the other headers (mylib.h) - and the

#   mylib-specific headers can simply use "#include <mylib-int.h>" to

#   obtain the stdint-types.

#

#   Remember, if the system already had a valid <stdint.h>, the

#   generated file will include it directly. No need for fuzzy

#   HAVE_STDINT_H things... (oops, GCC 4.2.x has deliberatly disabled

#   its stdint.h for non-c99 compilation and the c99-mode is not the

#   default. Therefore this macro will not use the compiler's stdint.h

#   - please complain to the GCC developers).
