Description David E. O'Brien freebsd_committer freebsd_triage 2004-11-11 01:30:25 UTC 
	Compiling with 'strict-aliasing' optimization breaks some [notable]
	ports.  GCC turns on 'strict-aliasing' optimization at all levels
	above -O[1], so explicitly turn it off when using compiling with
	"high" optimization levels.

How-To-Repeat: 	Build Firefox and other ports with -O2 (or -Os or -O3).

This patch has been rejected since it breaks ports if users doesn't use  
gcc, or any gcc-compatible compilers. 
BTW, thanks for your patch.
