I think what is more interesting is where e.g. the libraries in the build or installed tree are. Say on x86_64-linux in the build directory I have find gcc -name libgcc_s.so.\* -o -name libgcc.a gcc/libgcc.a gcc/32/libgcc.a gcc/32/libgcc_s.so.1 gcc/libgcc_s.so.1 What do you get with find gcc -name libgcc_s\*.dll -o -name libgcc.a ?
