  • base_sp/Makefile.am, hello/Makefile.am, iostream/Makefile.am, loopback/Makefile.am, nsecs/Makefile.am, pppd/Makefile.am, ticker/Makefile.am, ticker/system.h, unlimited/Makefile.am: Add optional managers to Makefiles. Clean up test cases so last output line follows END OF pattern. Make sure test case all run. All tests appeared ok on sis.
  • nsecs/init.c: Commit hack so test will compile when POSIX is disabled. Remove hack when clock_gettime() is present even when --disable-posix.
  • Property mode set to 100644
