Subject cvs commit: apache-2.0/src/lib/apr/helpers config.guess config.sub
Date Fri, 14 Jul 2000 18:06:01 GMT
rbb         00/07/14 11:06:00

  Added:       src/lib/apr/helpers config.guess config.sub
  Log:
  Move config.guess and config.sub from src/lib/apr to src/lib/apr/helpers.
  This is the first step in allowing APR to build on it's own again.

  # This script attempts to guess a canonical system name similar to
  # config.sub.  If it succeeds, it prints the system name on stdout, and
  # exits with 0.  Otherwise, it exits with 1.
  #
  # The plan is that this can be called by configure scripts if you
  # don't specify an explicit system type (host/target name).
  #
  # Only a few systems have been added to this list; please add others
