> Linking with gcc 4.0.2 gives many unsats for member functions of class templates explicitly instantiated in the library. For example:
> gcc -c -I/build/sebor/dev/stdlib/include/ansi -D_RWSTDDEBUG   -pthreads -D_RWSTD_USE_CONFIG -I/build/sebor/gcc-4.0.2-15s/include -I/build/sebor/dev/stdlib/include -I/build/sebor/dev/stdlib/examples/include  -pedantic -nostdinc++ -g  -Wall -W -Wcast-qual -Winline -Wshadow -Wwrite-strings -Wno-long-long  /build/sebor/dev/stdlib/examples/tutorial/alg7.cpp
> gcc alg7.o -o alg7 -pthreads -L/build/sebor/gcc-4.0.2-15s/lib -lstd15s  -lsupc++ -lm
> Undefined                       first referenced
>  symbol                             in file
> std::basic_string<char, std::char_traits<char>, std::allocator<char> >::substr(unsigned int, unsigned int) constalg2.o
> ld: fatal: Symbol referencing errors. No output written to alg2
> collect2: ld returned 1 exit status
> make: *** [alg2] Error 1
