[petsc-dev] broken options handling with intel 16.0 compilers on mac OS

[Jeff Hammond]

For what it's worth, I have actually used get_command_argument in my own
code and just now confirmed that it works just fine with Intel 16 in a
small test program.  It would be helpful to disambiguate that from all the
shared library discussion.

The other solution is to use ISO C11* as God intended and stop mucking
around with all these flowery languages.

Jeff

* It is true that no compiler yet supports C11 threads, but that is because
C compiler developers know better than to troll the PETSc team with
programming atrocities like threads.
