$ g++ -O2 -D_GLIBCXX_CONCEPT_CHECKS l.cxx 2>&1| wc
57 565 13383
$ g++ -O2 l.cxx 2>&1| wc
18 156 2784
Output seems to contains the exact same number of bytes.
I don't understand what O2 was supposed to do here. I am only trying
to get human readable output from what I believe is implemented in gcc
now: concept checking.
Thanks
