   across libraries, so our data and the CRT data get intermingled).

   Starting with MSVC 5.0, we must also place the uninitialized data
   into its own section.  VC5 intermingles uninitialized data from the CRT
   between Emacs' static uninitialized data and its public uninitialized
   data.  A separate .bss section for Emacs groups both static and
   public uninitialized together.

   Note that unexw32.c relies on this fact, and must be modified
   accordingly if this section name is changed, or if this pragma is
   removed.  Also, obviously, all files that define initialized data
   must include config.h to pick up this pragma.  */
