Sorry I have misled.  However, it is a good thing that my foolish performance 
was a chance
that you noticed your mistake.

I have re-read NEWS. 
The option --enable-fortran-int64 enables to use "BLAS  LAPACK  QRUPDATE  
ARPACK"

SuiteSparse internally used BLAS and LAPACK and --enable-fortran-int64 makes 
SuiteSparse handle large arrays?

How about glpk  Qhull?
Are patches for two libraries required to use large arrays in these libraries?
