c++ error with sid bootstrap-gcc_3.2

[bemis <bemis at iol dot unh dot edu>]

Hello,
I hope someone reads this list.
This error occured on an 686 platform while compiling the toolchain with
bootstrap-gcc_3.2 baseline
Is this problem solved by adding hash to the namespace or a build error
on our part?

the name space looks like this

namespace sidutil

  // Make a string from an object by the default output-streaming
operator.
  template <typename Type>
  static std::string
  make_attribute (const Type& value)
  {
#if HAVE_SSTREAM

    stream << value;
    return stream.str ();
#elif HAVE_STRSTREAM_H
    ostrstream stream;
    stream << value;
    std::string result (stream.str (), stream.pcount ());
    stream.freeze (0);
    return result;
#else
#error "need <sstream> or <strstream.h>!"
#endif
