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.
