<TITLE>RE: One small hint for compilation time</TITLE>
</HEAD>
<BODY>
<P><FONT SIZE=2>My goal is not to speed up compilation by 1/3, but to spped up compilation time.</FONT>
</P>
<P><FONT SIZE=2>Last time I have compiled kde 3.2.1 I have used -Os (with gcc 3.3.3), not -O2 neither -O3.</FONT>
</P>
<P><FONT SIZE=2>Disabling the -Wall is as speedy as redirecting the stderr and stdout to >/dev/null ?</FONT>
