r264400:

  NO_MAN= has been deprecated in favor of MAN= for some time, go ahead
  and finish the job. ncurses is now the only Makefile in the tree that
  uses it since it wasn't a simple mechanical change, and will be
  addressed in a future commit.

r265836:

  Remove last two NO_MAN= in the tree. In both of these cases, MAN= is
  what is needed.

Fixed missing or broken library dependencies.

Tweaks for sigqueue tests:

2009-10-11T17:04:13+00:00

- slightly adjust code for style, sort headers.
- in sigqtest2, print received signals, to make it easy to see why test
  failed.
- in sigqtest2, job_control_test(), cover a race by adding sleep after
  child stopped itself to allow for SIGCHLD due to stop and exit to not
  be coalesced.

MFC after:	2 weeks

Add code to test queued SIGCHLD.

2005-11-08T09:19:44+00:00
