Often I want to see what extensions that GCC supports for C++. Some of this stuff is in the manual, but more often than not I end up finding docs on third party web sites, or on mailing lists. I'm wondering where the official docs are? For example: __FUNCTION__ __PRETTY_FUNCTION__ are useful GCC specific variables for C++, but I can't seem to find them documented in the manual. I only see them documented here: http://www.redhat.com/docs/manuals/enterprise/RHEL-4-Manual/gcc/function-names.html and mentioned on a few mailist lists. Is there some place that really lists everything? Thanks, Brendan
