The following mail from http://gcc.gnu.org/ml/gcc-patches/2001-11/msg02088.html shows how the decision to use the current interpreter name was made: > * From: Bo Thorsen <bo at sonofthor dot dk> > * To: gcc-patches at gcc dot gnu dot org, patches at x86-64 dot org > * Date: Fri, 30 Nov 2001 15:05:30 +0100 > * Subject: Fix dynamic linker name for x86-64 > * Organization: SuSE Labs > > The x86-64 ABI for linux states that the dynamic linker is called > /lib/ld-linux-x86-64.so.2.
