Oohhh. Is this a serious attempt at passing the buck? 8-)
(No, this post isn't serious and doesn't really merit a response).
Heh. In certain cases, ld indeed spends considerable time attempting

During incremental build, 'ld' spends noticeable amount of time removing
duplicate BINCL/EINCL info (on Mac OS X).
