Hi,

compiling this program with g++ 4.7.1 ...

             
             #include <boost/serialization/strong_typedef.hpp>
             BOOST_STRONG_TYPEDEF(uint32_t, LINKID_T)

             int main()
             {
                 LINKID_T lid = 0xffddee33;
                 return 0;
             }
             

I get

            
             error: conversion from 'unsigned int' to non-scalar type 'LINKID_T' requested

Looking at the header, the strong typedef struct defines assignment from uint32_t to LINKID_T ...

             D & operator=(const T & rhs) { t = rhs; return *this;}

... so what gives?

Cheers,
Jono
