Hi Michael and all you others!

I thought this was a simple problem: Just link with libgpp and that's it.
So I compiled Michael's program with my usual commandline and it did compile 
without errors or warnings. However, I tried to break the commandline down to 
the necessary arguments and I typed:

gxx TEST.cc -lgpp

But this resulted in:

f:/cccqcctf(.text+0x1e):TEST.cc: undefined reference to 
`String::operator=(char const *)'
f:/cccqcctf(.text+0x6b):TEST.cc: undefined reference to String::~String(void)'
f:/cccqcctf(.text+0x8a):TEST.cc: undefined reference to `String::String(char 
const *)'

So I got back to my original call to gxx and found out that I had to compile 
it with some optimizations to make it work:

So 

gxx test.cc -lgpp -O

will work.

What is going on here?
