What is this patch about? You have already replaced where these two macros are used with a single usage of another macro which covers both. So will this patch solve the initialization issue or what? Would you please explain more?

These were the only places in these two solvers where GSL_FN_FDF_EVAL_F or GSL_FN_FDF_EVAL_DF were used independently. If the function or its derivative shared some expensive calculations in common, then this could lead to inefficient initialization of the solver.

See attached patch.
