20070716 Adding "solver" gjh to some system-specific subdirectories. It computes the objective gradient (g), the constraint Jacobian (J), and the Hessian of the Lagrangian (H) at the current point (primal and dual variable values). The solver message shows commands to read these as params and delete the temporary file that conveys them. When multiple objectives are present, the first is used unless the objectives have suffix objweight ==> g is the gradient of the weighted sum of objectives.

Removing directory linux/libc5. 20081202 Update "solver" gjh in some system-specific subdirectories to incorporate bug fixes (20080807, 20080808, 20080828) in the AMPL/ Solver Interface Library.
