Are you using boost in a place other than the system include 
directories?  gcc shouldn't give these warnings for system headers, so I 
believe you are.  Assuming I'm right, you can work around the problem by 
specifying the include path as "-isystem /path/to/boost" rather than "-I 
/path/to/boost".  This is not very 'nice' or portable, but it's probably 
  fine for the duration of your warning sifting.

There can still be problems, though, if you use boost macros with old 
style casts in your own files.  IME, BOOST_STATIC_ASSERT is the worst 
offender (according to the docs it's because of compiler deficiencies). 
  That was what finally forced my to turn off -Wold-style-cast in some 
of my code.
