User applications can now invoke hypre routines from both C and Fortran 77

integer b, x

integer A

integer smg_solver

b = hypre_vector_NewVector(com, grid, stencil)

...

x = hypre_vector_NewVector(com, grid, stencil)

...

A = hypre_matrix_NewMatrix(com, grid, stencil)

...

smg_solver = hypre_smg_solver_new()

call hypre_smg_solver_SetMaxIter(smg_solver, 10)

call hypre_smg_solver_Solve(smg_solver, A, b, x)

call hypre_smg_solver_Finalize(smg_solver)
