commit 4456c7e55e9ee5fcd3ce660317240e822be03043
Author: Greg Hudson <ghudson at mit.edu>

    Get getopt from unistd.h (not getopt.h) in tests
    
    POSIX defines getopt to be declared in unistd.h, and HP-UX (as of
    version 11.31) does not appear to have getopt.h.  In test programs
    which currently include getopt.h and aren't currently built on
    Windows, include unistd.h or just assume we will get it via k5-int.h.
