> Linking with gcc 4.0.2 gives many unsats for member functions of class templates \

> -I/build/sebor/dev/stdlib/include/ansi -D_RWSTDDEBUG   -pthreads \
> -D_RWSTD_USE_CONFIG -I/build/sebor/gcc-4.0.2-15s/include \

> alg7 -pthreads -L/build/sebor/gcc-4.0.2-15s/lib -lstd15s  -lsupc++ -lm Undefined    \
> first referenced symbol                             in file
