Follow-up Comment #6, bug #50339 (project octave):
I should also say, my goal is for this to work now without needing --enable-64
since that is now the default.
The idea is that Octave will use 64-bit indexing internally, but will check
the BLAS to determine whether 64-bit indexing should be used for Fortran (and
other) libraries that depend on the BLAS. If the BLAS is determined to use
64-bit indexing, then we should attempt to use the -fdefault-integer-8 (or
equivalent) option to compile the Fortran bits of Octave. Since I only know
what the right option is for gfortran, users of other compilers will have to
supply this option.
Anyway, probably I just have the logic mixed up in the configure script.
