Thank you for the report. The gcc-6.1.gz manpage is generated automatically
from its texinfo source, by texi2pod.pl and then pod2man. If there's any
bug in
the manpage, the problem is more likely to be in pod2man, so it's better to
try to report to the perl package (which contains /usr/bin/pod2man).
Thanks,
Yixuan
