* configure.ac (AC_INIT): Changed version number to 0.3. (AX_CREATE_STDINT_H): Added macro invocation. (AC_CHECK_HEADERS): Added stdint.h. (AM_CONDITIONAL): Added GENERATE_STDINT_H. * Makefile.am (nobase_openwinceinc_HEADERS): Removed stdint.h. (nodist_openwinceinc_HEADERS): Added owce-stdint.h and conditionally added stdint.h. (stdint.h): Added explicit target to generate stdint.h. (CLEANFILES): Adde stdint.h. * acinclude.m4: New file. * stdint.h: File removed. git-svn-id: https://urjtag.svn.sourceforge.net/svnroot/urjtag/trunk@494 b68d4a1b-bc3d-0410-92ed-d4ac073336b7master

dnl @synopsis AX_CREATE_STDINT_H [( HEADER-TO-GENERATE [, HEDERS-TO-CHECK])]
|
||||
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...

|

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.

Accoding to Douglas Gwyn <gwyn@arl.mil>:
|
||||
"This spec was changed in ISO/IEC 9899:1999 TC1; in ISO/IEC
|
||||
9899:1999 as initially published, the expansion was required
|
||||
to be an integer constant of precisely matching type, which
|
||||
is impossible to accomplish for the shorter types on most
|
||||
platforms, because C99 provides no standard way to designate
|
||||
an integer constant with width less than that of type int.
|
||||
TC1 changed this to require just an integer constant
|
||||
*expression* with *promoted* type."
|
||||
|
||||
The trick used here is from Clive D W Feather.
