Thanks for the clarification. : > /usr/src/lib/libc/i386/sys/_amd64_get_fsbase.c: In function `_amd64_get_fsbase': : > /usr/src/lib/libc/i386/sys/_amd64_get_fsbase.c:40: warning: dereferencing type-punned pointer will break strict-aliasing rules : > : > without -fno-strict-aliasing. Not that I have any serious desire to run : > with -O2, just curious. : : -O2 isn't supported in /usr/ports without -fno-strict-aliasing also. : There are a few ports that aren't happy being compiled with any form of : -O2 (such as the old perl). That error message was within /usr/src.
