On  AIX 5.3-7.1 for this test I get these results - and 'make tests' seemed
to work fine
$ xlc polltest.c && ./a.out ; ./a.out limit
poll = 1, error: Error 0
poll = 1, error: Error 0

HP-UX 11.31 + HP Ansi C/C++
$ cc polltest.c && ./a.out ;  ./a.out limit
"polltest.c", line 27: warning #2181-D: argument is incompatible with
          corresponding format string conversion
         printf("poll = %d, error: %s\n", r, strerror(errno));
                                             ^

poll = 1, error: Error 0
poll = 1, error: Invalid argument

HP-UX 11.11-11.31 + gcc
$ gcc polltest.c && ./a.out ;  ./a.out limit
poll = 1, error: Error 0
poll = 1, error: Invalid argument
