I noticed the info gcc pages were in some ways more detailed, for instance
this optimisation page:
http://www-es.fernuni-hagen.de/cgi-bin/info2html?(gcc)Optimize%20Options
Are the gcc online manual documents maintained by different people from the
gcc info pages? Perhaps some aspects could be combined.
