------- Comment #2 from geoffk at gcc dot gnu dot org 2007-03-07 00:16 ------- The change to gccspec.c was made by Franz Sirl on 2001-06-16, revision 43421. The mail on gcc-patches is at <http://gcc.gnu.org/ml/gcc-patches/2001-04/msg01394.html>. There's further discussion at <http://gcc.gnu.org/ml/gcc-patches/2001-03/msg00427.html>. I think it's relying on the property that the GNU runtime is (always?) linked with the dynamic libgcc.
