  Modified:    lib/libc/stdlib  system.3 system.c
  Log:
  Submitted by: (based on code in "Advanced Programming in the Unix Environment"
  by W.Richard Ste vens. EINTR handling suggested by bde@freebsd.org).
  
  Code cleanup:
  
  1. Add missing return type.
  2. Replace 'union wait' by int.
  3. Use Posix-style signal handling instead of signal().
  4. Use fork() instead of deprecated vfork().
  5. Block signals before fork()'ing, instead of after.
  6. Return -1 if fork() fails, instead of 0.
  7. Add EINTR handling for waitpid() call.
  
  Also add claim of Posix conformance to man page.
