  24  * @file dynconfig.c
  25  *
  26  * @brief Global configurations, initialized to configured defaults.
  27  *
  28  * This file should be the only file that depends on path
  29  * configuration (--prefix, etc), so that if ./configure is re-run,
  30  * all programs will be appropriately updated.  Everything else in
  31  * Samba should import extern variables from here, rather than relying
  32  * on preprocessor macros.
  33  *
  34  * Eventually some of these may become even more variable, so that
  35  * they can for example consistently be set across the whole of Samba
  36  * by command-line parameters, config file entries, or environment
  37  * variables.
  38  *
  39  * @todo Perhaps eventually these should be merged into the parameter
  40  * table?  There's kind of a chicken-and-egg situation there...
