  Modified:    .        CHANGES
               build    apr_common.m4
  Log:
  Add parameter to APR_SUBDIR_CONFIG to drop options passed to configure
  before the subdir's configure is invoked.
  
  Also, add documentation notes on what this macro does and autoconf version
  caveats that need to be watched out for!
  
  Inspired by:	Jeff's patch to httpd-2.0 (which was inspired by me on dev@httpd)

  +dnl Note: Older versions of autoconf do not single-quote args, while 2.54+

  +dnl to put up with more autoconf craziness.  I give up.
