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). +# +# LICENSE +# +# Copyright (c) 2008 Guido U.
