Subject: [PATCH] flashprog: Apply patch for fixing compiler warnings

Quoting the original commit message:

Some toolchains complain that this shadows the global from <getopt.h>.
Alas,  toolchains seem inconsistent in the decision when to warn about
shadowing of globals from system headers and when not to.  Hence, just
rename `optarg' -> `opt_arg'.

Fixes compiler warnings on Darwin and enables building.
