Hmm, there are a couple of other tests using -fpie on darwin:
./g++.dg/parse/attr-externally-visible-1.C:/* { dg-options "-O3 -fwhole-program
-fpie" { target *-*-darwin* } } */
./g++.dg/other/first-global.C:/* { dg-options "-fpie" { target *-*-darwin* } }
*/
./gcc.dg/pie-link.c:/* { dg-options "-fpie" } */


On closer inspection, the first two are compile-only, so the linker isn't
invoked.  The latter is only run on darwin[912], which I assume means darwin9
or later (10, 11, 12, 20, 21, 22, ...).

So I guess you're using an older version of darwin that doesn't know about pie.
 In that case I guess your patch (with the typo fixed) is the best option.

Will you be installing it?

Thanks,
