--- Comment #4 from M Joshua Ryan <luser.droog at gmail dot com> --- Created attachment 36789 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=36789&action=edit .i file left by `make CFLAGS='-g -O2 -save-temps'` I think this is the correct file now. I see "0" "0" and "1" instead of the version symbols discovered above.
