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