While testing the state of gfortran in gcc trunk at -m64 on MacOS X 10.4 I discovered a huge number of test failures (848 compared to 26 with -m32). Almost all of these failures appear to be due to two undefined symbols in libgfortran's shared library in the ppc64 version...
http://gcc.gnu.org/ml/fortran/2006-08/msg00112.html The symbols, ___divti3 and ___umodti3, are not present in darwin-libgcc.10.4.ver or darwin-libgcc.10.5.ver found in gcc/config/rs6000 but they are present in the libgcc-std.ver in the gcc directory. I haven't found anything in bugzilla about this issue, however it really should be addressed before gcc 4.2 is released. Jack
