360 Starting with MSVC 5.0, we must also place the uninitialized data
361 into its own section. VC5 intermingles uninitialized data from the CRT
362 between Emacs' static uninitialized data and its public uninitialized
363 data. A separate .bss section for Emacs groups both static and
364 public uninitialized together.
366 Note that unexw32.c relies on this fact, and must be modified
367 accordingly if this section name is changed, or if this pragma is
368 removed. Also, obviously, all files that define initialized data
369 must include config.h to pick up this pragma. */
