Given this file:

#include        "int.List.h"
#include        <String.h>

with int.List.h generated as:

genclass int val List
genclass int val defs

(or with ref -- doesn't matter)
g++ produces the error message:

/usr/local/lib/g++-include/streambuf.h:94: `append' redeclared as different kind of symbol
int.List.h:87: previous declaration of `class intList append (class intList&, class intList&)'

I regard this as either a bug in libg++ (namespace) or a bug in g++.

PS There is an easy workaround: reverse order of including files.

Since the former definition of append is non-standard, and only
defined in "compatibily-mode" for the old stream.h, I suggest replacing
#include <stream.h> by #include <iostream.h> in String.h (and
most other places).  I don't know what will break.  I'll find out
for the next release ...
