Look at gcc/mklibgcc.in in the 4.0 branch. They add a dummy eh_dummy.o file to libgcc_eh.a to work around this. We had Eric Botcazou backport it to the 3.4 branch for us but a PR hasn't been created. I don't know if its considered a safe enough fix. I haven't tested it yet but I'll attach the patch to this PR. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=24718
