This has gone away after I built gambc40b13 with
env CC='gcc -mcpu=970 -m64 -force_cpusubtype_ALL' ./configure --enable-single-host
and
[descartes:~/programs/gambc40b13] lucier% gcc -v Using built-in specs. Target: powerpc-apple-darwin8.1.0 Configured with: ../configure --prefix=/pkgs/gcc-4.0.0-apple --with-gmp=/pkgs/gmp-4.1.4 --with-mpfr=/pkgs/gmp-4.1.4 --enable-languages=c,c++,f95 Thread model: posix gcc version 4.0.0 (Apple Computer, Inc. build 5018)
So it seems to be a problem with Apple's
[descartes:~/programs/gambc40b13] lucier% /usr/bin/gcc -v Reading specs from /usr/lib/gcc/powerpc-apple-darwin8/4.0.0/specs Configured with: /private/var/tmp/gcc/gcc-4061.obj~8/src/configure --disable-checking --prefix=/usr --mandir=/share/man --enable-languages=c,objc,c++,obj-c++ --program-transform-name=/^[cg][^+.-]*$/s/$/-4.0/ --with-gxx-include-dir=/include/gcc/darwin/4.0/c++ --build=powerpc-apple-darwin8 --host=powerpc-apple-darwin8 --target=powerpc-apple-darwin8 Thread model: posix gcc version 4.0.0 20041026 (Apple Computer, Inc. build 4061)
as distributed. (And don't blame the FSF, Apple's distributed compiler was branched on October 26, 2004, when the FSF sources still had a lot of bugs; the FSF 4.0.0 compiler wasn't released until last month.)
Marc: It will be *really cool* when I can run a 64-bit Gambit on my 2GHz G5.
