[Dominique Dhumieres]

Revision 180821 breaks bootstrap on x86_64-apple-darwin10:

../../work/gcc/collect2.c: In function 'int main(int, char**)':
../../work/gcc/collect2.c:1094:7: error: unused variable 'object_nbr' [-Werror=unused-variable]
cc1plus: all warnings being treated as errors

Note that I did not find any entry for this revision in gcc-patches@gcc.gnu.org.
