[Geoff Keating]

Hi HJ,

+2001-07-13  H.J. Lu  (hjl@gnu.org)
+
+	* config/elfos.h (UNIQUE_SECTION): Enable .bss section.

You didn't say on which target you tested this patch, and it broke the
build on x86-linux, so I have reverted it.

Please test the patch on x86-linux before resubmitting it as it is
known to have problems on this platform.
