Python3 uses the following addition in configure.in and it fixes the issue on
macosx 10.5:

# Enabling LFS on Solaris (2.6 to 9) with gcc 2.95 triggers a bug in
# the system headers: If _XOPEN_SOURCE and _LARGEFILE_SOURCE are
# defined, but the compiler does not support pragma redefine_extname,
# and _LARGEFILE64_SOURCE is not defined, the headers refer to 64-bit
# structures (such as rlimit64) without declaring them. As a
# work-around, disable LFS on such configurations

use_lfs=yes
AC_MSG_CHECKING(Solaris LFS bug)
AC_TRY_COMPILE([
#define _LARGEFILE_SOURCE 1
#define _FILE_OFFSET_BITS 64
#include <sys/resource.h>
],struct rlimit foo;,sol_lfs_bug=no,sol_lfs_bug=yes)
AC_MSG_RESULT($sol_lfs_bug)
if test "$sol_lfs_bug" = "yes"; then
  use_lfs=no
fi

if test "$use_lfs" = "yes"; then
# Two defines needed to enable largefile support on various platforms
# These may affect some typedefs
AC_DEFINE(_LARGEFILE_SOURCE, 1, 
[This must be defined on some systems to enable large file support.])
AC_DEFINE(_FILE_OFFSET_BITS, 64,
[This must be set to 64 on some systems to enable large file support.])
fi
