It was for me, too.
But it is quite simple: c++ as a official standard only since last year. 
Before that there only were drafts. So the different implementations (aka 
compilers) all had their own string class. The GNU string class, that you can 
find in libgpp, is the one with the capital S (included with <_string.h>. The 
new c++ library libstdcxx contains the string class that the standard 
prescribes (included with <string>).
But over the long run nobody needs two c++ libraries, so libstdcxx will take 
the place of libgpp, which allready happened when it comes to the default 
library used for djgpp c++ programs.
The documentation side of that, is the dark side. There are some documents on 
the net, and thanks to the standard they should apply to any compiler. But I 
don't think that there is any GNU documentation (and by the way the docs for 
libgpp were excellent).

Seeing clearer now?

PS: Please don't ask, why they dropped the .h for the include files. This 
one's the real mystery.
