+  This file contains the "fatal error" callback routine required by the
+  "minimal" (silent, non-stdio) setup of the bzip2 compression library.
+
+  The fatal bzip2 error bail-out routine is provided in a separate code
+  module, so that it can be easily overridden when the UnZip package is
+  used as a static link library. One example is the WinDLL static library
+  usage for building a monolythic binary of the Windows application "WiZ"
+  that supports bzip2 both in compression and decompression operations.
+
+  Contains:  bz_internal_error()      (USE_BZIP2 only)
