Remove deprecation warning for -I- (gcc-4.6.2)

Patch against gcc-4.6.2 to remove the deprecation warning for -I- since there's
no complete replacement for it yet.  This will probably ruffle some feathers;
sorry about that.

FWIW, it's my intention to keep this patch updated (at
http://achurch.org/patch-pile/#gcc) until either it's officially undeprecated
or a replacement for the "ignore source directory" functionality of -I- is
available.
