[C++-sig] Pyste bugs again

I hate to be a bore but the patches I submitted here last time have 
not been implemented in the latest CVS version.

This means that quite simply pyste DOES NOT WORK on MSVC.

Bug 1: Declaring an unnamed namespace in the pyste output causes 
MSVC7.1 to gobble memory until infinity.

My solution: Alter Save() in SingleCodeUnit.py:

            if declaration:
                pyste_namespace = namespaces.pyste[:-2]            
                if pyste_namespace:
                    fout.write('namespace %s {\n\n' % 
pyste_namespace)
                fout.write(declaration) 
                if pyste_namespace:
                    fout.write('\n}// namespace %s\n' % 
pyste_namespace)
                fout.write(space)

This simply doesn't write out a namespace declaration if it's 
unnamed.

Bug 2: Unnamed enums are still being called "$_xx". MSVC does not 
like symbols starting with $. Furthermore the export_values() 
facility is still not being employed.

My solution: Alter Export() in EnumExporter.py:

    def Export(self, codeunit, exported_names):
        if not self.info.exclude:
            indent = self.INDENT
            in_indent = self.INDENT*2
            rename = self.info.rename or self.enum.name
            full_name = self.enum.FullName()
            if rename[0:2] == "$_" or rename == '._0':
                global uniqueTypeCount
                full_name = 'UniqueInt<%d>' % uniqueTypeCount
                uniqueTypeCount+=1
                rename = "unnamed"
            code = indent + namespaces.python
            code += 'enum_< %s >("%s")\n' % (full_name, rename)
            for name in self.enum.values:         
                rename = self.info[name].rename or name
                value_fullname = self.enum.ValueFullName(name)
                code += in_indent + '.value("%s", %s)\n' % (rename, 
value_fullname)
            code += in_indent + '.export_values();\n\n'
            codeunit.Write('module', code)
            exported_names[self.enum.FullName()] = 1

Cheers,
Niall
