The code in question compiles and runs successfully using:
g++ -o striner striner.cpp.cpp
where striner.cpp is the sourcefile I copied your code into.
I am testing on a pc running Cygwin and gcc-3.1.1. If you use:
gcc -o striner striner.cpp
It generates a lot of errors, in my case something like:

This is expected, as the g++ command grabs more C++ specific items to link.
Hope that helps.
