[boost] [#pragma once]

I've worked with the MSVC, Sun and GCC compilers.

 

Each one of them supports #pragma once.  Is there any reason to wrap
this pragma within #ifdefs? Are there any compilers out there today that
don't support this #pragma?

 

#if defined( _MSC_VER ) && ( _MSC_VER >= 1020 )

# pragma once

#endif

 

Could we change this coding pattern so that it no longer looks like MSVC
is being selfish?
