Evening I just googled: gcc implicit-function-declaration This page comes first. https://gcc.gnu.org/onlinedocs/gcc-4.0.1/gcc/Warning-Options.html I have raised this a few months ago https://www.spinics.net/lists/gcchelp/msg51514.html Can each gcc onlinedocs pages have a banner stating they are not the latest version? How about setting the robots.txt to exclude all old versions? Only keep the latest version and and development version Cheers, Jonny
