[xsd-users] Warning while using maxUnsignedInt with c++98 standard with xsd3.3

[Florin Hillebrand]

Hi all,

first my environment:

- ubuntu 10.04 on x86 32bit
- xsd3.3
- g++-4.4 with -stdc=c++98 -Wall compiler options.

I have an xsd which generates me a element with an attribute of type
xsd:unsignedInt with a default value. The default value has to be the
maximal unsigned int value (4294967295).

----------
<xsd:element name="Element">
  <xsd:complexType>
      <xsd:attribute name="attr" use="optional" type="xsd:unsignedInt" default="4294967295" />
  </xsd:complexType>
</xsd:element>
----------

When xsd 3.2 generated the cxx-tree i got back a constant and a method:

----------
const Element::attr_type Element::attr_default_value_ (
        ::xsd::cxx::tree::traits< ::xml_schema::unsigned_int, char >::create (
          ::std::string ("4294967295"), 0, 0, 0));


const Element::attr_type& Element::attr_default_value () {
        return attr_default_value_;
      }
---------

This works well without any compiler warnings, but when I updated xsd to
3.3 it generates me:

---------
const Element::attr_type& Element::attr_default_value () {
        return 4294967295;
      }
---------

This generates a g++ warning (Warnings treaded as errors):

------------
error: this decimal constant is unsigned only in ISO C90
------------

c++98 standard says:

---cite---- ISO/IEC 14882:1998(E)  page 42 point 2 ------
If it is decimal and has no suffix, it has
the first of these types in which its value can be represented: int,
long int;
-----------

So this won't work, but:

---cite---- ISO/IEC 14882:1998(E)  page 42 point 2 ------
If it is suffixed by u or U, its type is the first of these types in
which its value can be represented: unsigned int, unsigned long int;
-----------

This would work but i can't append an u or U to the default value,
because regex wouldn't pass.

I would appreciate any suggestions.

With kind regards,

Florin
