Description

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
