[petsc-dev] parsing FORTRAN command line on Cray XC40

[Satish Balay]

All of this code [related to fortran command line processing] is old hackey.

Does the following change fix the issue for you?

Perhaps there is a way to remove all of this [c] code - and use a
single fortran routine [that works with all fortran compilers] - to
process command line args..
