I don't know if it's related, but roughly since the GCC 4.0 upload, I
get strange assembler warnings for perfectly valid C++ programs:
/tmp/ccnkt3NO.s:697: Warning: ignoring changed section attributes for .gnu.linkonce.t._ZN4SigC7Signal0IvNS_7MarshalIvEEE5emit_EPv
/tmp/ccnkt3NO.s:7101: Warning: ignoring changed section attributes for .gnu.linkonce.t._ZN9undo_listD0Ev
/tmp/ccnkt3NO.s:7285: Warning: ignoring changed section attributes for .gnu.linkonce.t._ZN9undo_listD1Ev
Is it safe to ignore these warnings? What is causing them?
