Hi,

Any use of BOOST_SCOPE_EXIT in 1.57 seems to emit warning C4003 on MSVC 
2012 and 2013:
   warning C4003: not enough actual parameters for macro 'BOOST_PP_EXPAND_I'

Uncomment either line to suppress the warning.

Is BOOST_PP_VARIADICS enabled by mistake for MSVC (especially 2013)? 
Should I explicitly set BOOST_PP_VARIADICS=0 for MSVC?

Despite the warning, the code appears to work fine (i.e., the block of 
code gets properly called).

Thanks,
Filip

   return 0;
