From 525cddd2bcea4c565d6dd1d2d55dd1de1a476b67 Mon Sep 17 00:00:00 2001 From: Rainer Orth Date: Sat, 18 Jan 2014 10:07:52 +1300 Subject: libtool: opt_duplicate_compiler_generated_deps is harmful on Solaris Fix for http://debbugs.gnu.org/cgi/bugreport.cgi?bug=16452. * build-aux/ltmain.in (libtool_validate_options): disable the opt_duplicate_compiler_generated_deps optimization for Solaris2 so that gcc-4.9+ compiled C++ code with -Wl,-Bdirect on 64-bit Solaris x86 can avoid unwinding failures caused by accidental mixing of the libc and libgcc_s unwinders in a single executable.
