Thanks for the report.
AIX 6.1 appears to have libperfstat, so is using this code:

# if defined HAVE_LIBPERFSTAT
#  include <libperfstat.h>
#  include <sys/proc.h>
#  ifndef SBITS
#   define SBITS 16
#  endif
# endif

declaration of "struct protosw".

Please see if there is a man page for libperfstat.
It may tell which headers must be included there.
Once we know that we should be able to fix it.
