--- Comment #15 from Larry Baker <baker at usgs dot gov> 2012-11-20 22:24:46 UTC --- Jakub, I undertand the reason for the --with-host-libstdcxx option. The documentation for --with-host-libstdcxx doesn't say anything about the side effect of changing the LINKER from $(CXX) to $(CC). It is that effect that I believe is undesirable, especially given the change of GCC's implementation language from C to C++.
