Oddball thing with GCC is that if you need to compile a C++ program that 
has a nonstandard C++ extension in the filename (eg: blah.c++ or 
similar), GCC's frontend won't know how to ultimately link it. The 
solution is not to compile it with the usual gcc command, but with the 
g++ command. This will invoke the C++ compiler directly (command line 
args are identical as those used for gcc) and take care of the 
unresolved symbols.

Also, as a side note, I would not suggest building a C++ application on 
anything older than GCC 3.0 using the STL, as the implementations before 
3.0 seem to be rather broken (missing classes, etc.)
