The whitelist in conform/linknamespace.pl covers both false positives and 
genuine but hard-to-fix bugs.  So these names should be added there with 
an appropriate comment.

# The following whitelisted symbols are also allowed for now.
#
# * Bug 17576: stdin, stdout, stderr only reserved with external
# linkage when stdio.h included (and possibly not then), not
# generally.
#
# * Bug 18442: re_syntax_options wrongly brought in by regcomp and
# used by re_comp.
#
# * False positive: matherr only used conditionally.  matherrf/matherrl are used
# by IA64 too for the same reason.
#
@whitelist = qw(stdin stdout stderr re_syntax_options matherr matherrf
                matherrl);
