Details: - Replaced the hard-coded calls to double-precision real syr, syr2, syrk, and syrk in the corresponding standalone test drivers in the 'test' directory with conditional branches that will call the appropriate BLAS interface depending on which datatype is enabled. Thanks to Madan mohan Manokar for this improvement. - CREDITS file update.
