I tried to add "-w" to CFLAG, however, it didn't work.

Any suggestions are appreciated.

This version is not in tree anymore. Please sync portage and try with latest stable version, unless you have a specific reason for using 10.2.8?

emerge --info please.

You should try to resolve the emerge errors with your portage tree synced, rather than keeping obsolete ones. That will take some time now, but you'll save more later.
