Has used egcs-g77 to successfully link any of the available compiler flavors (intel,watcom,microsoft) of the BLAS (basic lin. alg. subprogs) binary libraries available from the Intel site. g77 complains bitterly about the format of 2 of them. It reads the other one but then is unable to link the routines in. Thanks David Kebler New Mexico Tech, Math Dept. daneel@nmt.edu
