UMPACK functions have two letters to define the types of the arguments.
The first letter is either "z" or "d" defining whether the functions are
double complex or double. The second is either "i" or "l" defining if
the indexing arguments are int or long... The configuration script of
octave selects either "int" or "long" type for otave_idx_type, and the
same type will be used by the UMFPACK functions, and so there should be
nothing to do for 64-bit UMFPACK...
However, I do know that the COLAMD stuff including colamd and symamd is
not 64-bit safe, and similarly for the load/save code, these are things
that still have to be fixed... For the COLAMD stuff, the original author
Tim Davis is working on a replacement of COLAMD that wil address this
issue and will release it soon So I propose to do nothing there till
this new code is released...
