dnl @synopsis AC_COMPILE_CHECK_SIZEOF(TYPE [, HEADERS [, EXTRA_SIZES...]])
dnl
dnl This macro checks for the size of TYPE using compile checks, not
dnl run checks. You can supply extra HEADERS to look into. the check
dnl will cycle through 1 2 4 8 16 and any EXTRA_SIZES the user
dnl supplies. If a match is found, it will #define SIZEOF_`TYPE' to
dnl that value. Otherwise it will emit a configure time error
dnl indicating the size of the type could not be determined.
dnl
dnl The trick is that C will not allow duplicate case labels. While
dnl this is valid C code:
dnl
dnl switch (0) case 0: case 1:;
dnl
dnl The following is not:
dnl
dnl switch (0) case 0: case 0:;
dnl
dnl Thus, the AC_TRY_COMPILE will fail if the currently tried size
dnl does not match.
dnl
dnl Here is an example skeleton configure.in script, demonstrating the
dnl macro's usage:
dnl
dnl AC_PROG_CC
dnl AC_CHECK_HEADERS(stddef.h unistd.h)
dnl AC_TYPE_SIZE_T

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_COMPILE_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...
