#2724: extended_type_info_arg constructor calls base constructor with wrong
argument

     Type:  Bugs            |      Status:  new          
Milestone:  Boost 1.38.0    |   Component:  serialization
  Version:  Boost 1.37.0    |    Severity:  Problem      
 Keywords:                  |  
----------------------------+-----------------------------------------------
 In the file libs/serialization/src/extended_type_info.cpp, the constructor
 for the class extended_type_info_arg calls the base class constructor
 extended_type_info with an argument of NULL. The extended_type_info
 constructor takes an unsigned int argument, and NULL is not necessarily an
 unsigned int or even convertible to such. (See C.2.2.3 of C++98 standard.)
 Changing the argument to a constant 0 (or a named constant with that
 value) fixes the local problem, and doesn't conflict with either of the
 other existing classes derived from extended_type_info.

 I noticed this problem in 1.38beta2, due to a warning on one of the
 platforms I'm using, but it looks like it's been this way "forever".
