#include <strstream>
Does not work because __STL_BEGIN_NAMESPACE is undefined
before the first reference.

It is a regression from gcc-2.95.2 (which used to work).

I guess this is too late for gcc-3.0 :-(

configuration options (during build):
../gcc/configure --prefix=/afs/haifa/proj7/gec2/gnu --enable-languages=c++ --disable-multilib

Compiler message:
$ gcc -c f.cc
