Author: mrs Date: Fri Mar 19 10:19:52 2010 New Revision: 157563 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=157563 Log: PR ada/42554 * configure.ac: Only pass -c to ranlib for darwin9 and earlier. * configure: Regenerate. Modified: trunk/ChangeLog trunk/configure trunk/configure.ac to gcc/configure. This eliminates the various bootstrap failures in PR49992, caused by duplicate symbols between errors.c and diagnostic.c due to radar 6320843, "duplicate symbols from static libraries not properly ignored". Since radar 6320843 only effects Xcode 3.2 and later, there is little reason to change the logic as applied in r157563 of only inhibiting the use of the '-c' flag with ranlib on darwin10 and later. Bootstrap and regression tested on x86_64-apple-darwin10. http://gcc.gnu.org/ml/gcc-testresults/2011-08/msg01198.html Okay for gcc trunk?
