fyi: glibc-2.2.3 zero-initialized .data variables

["Adam J. Richter" <adam at yggdrasil dot com>]

	In case anyone is interested, here is a list of zero-initialized
.data variables in glibc-2.2.3.  There are only 1876 bytes, mostly due
to __ypdomainname in libnsl (1028 bytes) and three variables named
ext_end in libnss_compat (320 bytes).  This output was generated from
a program that I am working on and expect to release under GPL in the
next few days.  So, if there were any false positives or missed
positives, I would be happy to hear about it.
