From: http://gcc.gnu.org/gcc-3.3/changes.html

GCC 3.3.1 automatically places zero-initialized variables in the .bss
section on some operating systems. Versions of GNU Emacs up to (and
including) 21.3 will not work correctly when using this optimization;
you can use -fno-zero-initialized-in-bss to disable it.

so presumably gcc 3.2 (which we still support, right?) does not do this
(and puts such variables in .data).
