For AIX 4.3.2 (not 4.3.3 or 5.x), <sys/inttypes.h> has:
#define PRId8 %hd
#define PRId16 %hd
#define PRId32 %d
#if defined(__64BIT__)
#define PRId64 %ld
#else
#if defined(_LONG_LONG)
#define PRId64 %lld
#endif
Because it has the '%', this screws up the autoconf test:
checking whether inttypes.h defines the PRI[doxu]64 macros... no
because it assumes the PRI macros do not contain a %:
AC_MSG_CHECKING([[whether inttypes.h defines the PRI[doxu]64 macros]])
AC_COMPILE_IFELSE(
...
[
AC_LANG_SOURCE(
[[
#include <inttypes.h>
#include <stdio.h>
#include <sys/types.h>
main()
{
printf("%" PRId64 "\n", ($ac_ethereal_uint64_t_type)1);
printf("%" PRIo64 "\n", ($ac_ethereal_uint64_t_type)1);
printf("%" PRIx64 "\n", ($ac_ethereal_uint64_t_type)1);
printf("%" PRIu64 "\n", ($ac_ethereal_uint64_t_type)1);
}
]])
],
As the test fails, ethereal defines PRId64. But, because the IBM C
compiler does not like re#defining a macro, ./configure eventually
fails:
...
"/usr/include/sys/inttypes.h", line 258.9: 1506-213 (S) Macro name
PRId64 cannot be redefined.
"/usr/include/sys/inttypes.h", line 258.9: 1506-358 (I) "PRId64" is
defined on line 24 of conftest.c.
"/usr/include/sys/inttypes.h", line 324.9: 1506-213 (S) Macro name
PRIo64 cannot be redefined.
"/usr/include/sys/inttypes.h", line 324.9: 1506-358 (I) "PRIo64" is
defined on line 25 of conftest.c.
...
What is the best way to fix this? I think the easiest fix is to define
the PRIx64 macros with % and have two autoconf tests for PRI, one
testing without the '%', and one with.
