argp uses getopt. getopt uses global variables to keep state. And as
far as I know getopt doesn't use tricks like thread local storage.
So it's not reentrant.

My hacked argp,
http://www.lysator.liu.se/~nisse/misc/argp-standalone-1.2.tar.gz
doesn't depend on getopt, and doesn't use global variables.
