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. Source = /netlib/ampl/solvers/examples/gjh.c.
Removing directory linux/libc5.

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