 C.6 System-wide configuration and settings
 ==========================================
 
 GDB can be configured to have a system-wide init file; this file will be
 read and executed at startup (What GDB does during startup
 Startup.).
 
    Here is the corresponding configure option:
 
 '--with-system-gdbinit=FILE'
      Specify that the default location of the system-wide init file is
      FILE.
 
    If GDB has been configured with the option '--prefix=$prefix', it may
 be subject to relocation.  Two possible cases:
 
    * If the default location of this init file contains '$prefix', it
      will be subject to relocation.  Suppose that the configure options
      are '--prefix=$prefix --with-system-gdbinit=$prefix/etc/gdbinit';
      if GDB is moved from '$prefix' to '$install', the system init file
      is looked for as '$install/etc/gdbinit' instead of
      '$prefix/etc/gdbinit'.
 
    * By contrast, if the default location does not contain the prefix,
      it will not be relocated.  E.g. if GDB has been configured with
      '--prefix=/usr/local --with-system-gdbinit=/usr/share/gdb/gdbinit',
      then GDB will always look for '/usr/share/gdb/gdbinit', wherever
      GDB is installed.
 
    If the configured location of the system-wide init file (as given by
 the '--with-system-gdbinit' option at configure time) is in the
 data-directory (as specified by '--with-gdb-datadir' at configure time)
 or in one of its subdirectories, then GDB will look for the system-wide
 init file in the directory specified by the '--data-directory'
 command-line option.  Note that the system-wide init file is only read
 once, during GDB initialization.  If the data-directory is changed after
 GDB has started with the 'set data-directory' command, the file will not
 be reread.
