    building: #include <unistd.h> into plutomain.c
    
    Since plutomain.c is calling functions like access() which are defined
    in <unistd.h> the #include should be needed.  On GNU/Linux systems,
    with USE_LIBCAP_NG=true, the problem was hidden by <cap-ng.h> sucking
    in the header (on BSD, its <getopt.h>).
