make buildkernel error

[Unga]

Hi all

I'm getting following compile error for /usr/src/sys/i386/i386/genassym.c :
cc1: error: unrecognized command line option "-mno-align-long-strings"
cc1: error: unrecognized command line option "-fformat-extensions"
*** Error code 1

I'm using gcc version 4.3.1.

Does this means above options are not compatible with gcc version 4.3.1?

Is it safe to remove above options from kernel sources and recompile or what am I suppose to do now?

This is RELENG_7, cvsup a month ago.

Appreciate your reply very much.

Kind regards
