gdtoa - Changes to libc

[Antonio Huete Jimenez <ahuete.devel@xxxxxxxxx>]

There has been a security update on libc: http://www.securityfocus.com/bid/35510

You are encouraged to rebuild & reinstall libc after this change:

# cd /usr/src/lib/libc
# make obj
# make depend
# make
# make install

Also, a reboot is recommended after installing the new libc.

Cheers,
Antonio Huete
