Apache and mod_php4 problems

Hi! I am having this problem: If apache was compiled with -DLARGEFILE_SOURCE and -D_FILE_OFFSET_BITS=64, mod_php4 doesn't work. Looks like stat structure has different sizes in apache and mod_php4.c, as a result php_xbihack_handler crashes, b'ze request_rec is garbage. Compiling mod_php4 with the same flags doesn't seem to help. The fix is to move struct stat finfo to the end of request_rec, but it seems to be a hack. Does anybody have a better idea? Thanks.
