| g++-3.4 -c  -fPIC -I. -I.. -I../liboctave -I../src -I../libcruft/misc  -DHAVE_CONFIG_H    oct-fstrm.cc -o pic/oct-fstrm.o
| oct-fstrm.cc: In constructor `octave_fstream::octave_fstream(const std::string&, std::_Ios_Openmode, oct_mach_info::float_format)':
| oct-fstrm.cc:55: error: no matching function for call to `std::basic_fstream<char, std::char_traits<char> >::open(const char*, std::_Ios_Openmode&, int)'

The code in question is:

  octave_fstream::octave_fstream (const std::string& nm_arg,
				  std::ios::openmode arg_md,
				  oct_mach_info::float_format ff)
    : octave_base_stream (arg_md, ff), nm (nm_arg)
  {

  #if CXX_ISO_COMPLIANT_LIBRARY

    fs.open (nm.c_str (), arg_md);

  #else
    // Override default protection of 0664 so that umask will appear to
    // do the right thing.

    fs.open (nm.c_str (), arg_md, 0666);  // LINE 55

  #endif

    if (! fs)
      {
	using namespace std;

	error (strerror (errno));
      }
  }


What happened when you ran configure?  Why is
CXX_ISO_COMPLIANT_LIBRARY not defined?
