[boost] [utility] Patch for typed_in_place_factory.hpp

From: Markus Schöpflin (markus.schoepflin_at_[hidden])

Hello,

this header file contains the following code:

   void* apply (void* address, std::size_t n) const
   {
     for(char* next = address = this->apply(address); !! --n;)
       this->apply(next = next+sizeof(T));
     return address;
   }

Tru64/CXX rightly voices objections when compiling this code, used for 
example by optional_test_inplace:

cxx: Error: ../../../boost/utility/typed_in_place_factory.hpp, line 57: a
           value of type "void *" cannot be used to initialize an entity of
           type "char *" (D:badinittyp)
     for(char* next = address = this->apply(address); !! --n;)
---------------------^

Attached patch contains a fix for this. OK to commit?

Regards,
Markus
