Hi,The configure-script seems to misconfigure the postdep_objects_CXX when CFLAGS contains "-flto -fuse-linker-plugin" (using binutils-2.21.51.0.1 and gcc-4.6-20101127):
eg (libtool-2.4.1a):CFLAGS="-flto -fuse-linker-plugin" CXXFLAGS="-flto -fuse-linker-plugin" ./configure && grep postdep_objects libtool
postdep_objects="/usr/lib/gcc/i686-pc-linux-gnu/4.6.0/crtendS.o /usr/lib/gcc/i686-pc-linux-gnu/4.6.0/../../../crtn.o /usr/lib/gcc/i686-pc-linux-gnu/4.6.0/../../../crti.o /usr/lib/gcc/i686-pc-linux-gnu/4.6.0/crtbeginS.o /usr/lib/gcc/i686-pc-linux-gnu/4.6.0/crtendS.o /usr/lib/gcc/i686-pc-linux-gnu/4.6.0/../../../crtn.o"
instead of:postdep_objects="/usr/lib/gcc/i686-pc-linux-gnu/4.6.0/crtendS.o /usr/lib/gcc/i686-pc-linux-gnu/4.6.0/../../../crtn.o"
This does not happen when only -flto or only -fuse-linker-plugin is in CFLAGS, it only happens when they are both in CFLAGS...
I suppose the error comes from the check in libtool.m4.... Thanks for looking in to this! Brice
