It is xz-4.999.9beta.tar.gz from http://tukaani.org/xz/. I was using gcc 4.2, but now 4.3 and I haven't retried with 4.3.5 yet. configure says: # Generated by GNU Autoconf 2.64 for XZ Utils 4.999.9beta. "For XZ Utils" sounds to me like maybe custom. configure, and I think this helpful part, says: # ac_fn_c_find_uintX_t LINENO BITS VAR # ------------------------------------ # Finds an unsigned integer type with width BITS, setting cache variable VAR # accordingly. ac_fn_c_find_uintX_t () { as_lineno=${as_lineno-"$1"} as_lineno_stack=as_lineno_stack=$as_lineno_stack { $as_echo "$as_me:${as_lineno-$LINENO}: checking for uint$2_t" >&5 $as_echo_n "checking for uint$2_t... " >&6; } if { as_var=$3; eval "test \"\${$as_var+set}\" = set"; }; then : $as_echo_n "(cached) " >&6 else eval "$3=no" for ac_type in uint$2_t 'unsigned int' 'unsigned long int' \ 'unsigned long long int' 'unsigned short int' 'unsigned char'; do cat confdefs.h - <<_ACEOF >conftest.$ac_ext /* end confdefs.h. */ $ac_includes_default int main () { static int test_array [1 - 2 * !(($ac_type) -1 >> ($2 - 1) == 1)]; test_array [0] = 0 ; return 0; } _ACEOF ,,, > And am I correct that this was on: > > Target: alpha-dec-osf4.0g Yes. > Did the configure.ac use the documented AC_TYPE_INT64_T and > AC_TYPE_UINT64_T macros, or is it using a home-brewed approach? configure.ac says: AC_TYPE_UINT8_T AC_TYPE_UINT16_T AC_TYPE_INT32_T AC_TYPE_UINT32_T AC_TYPE_INT64_T AC_TYPE_UINT64_T AC_TYPE_UINTPTR_T I can try regenerating the configure file, later (might be a while, machine owner going on vacation and powering off I believe). btw: if you were to check for long long first, then long, then int, that'd help, right?
