Use native typeof support for Oracle Solaris Studio C++ compiler

[Maxim Kartashev <maxim.kartashev@…>]

Oracle Solaris Studio (former SunStudio) C++ compiler supports native typeof since version 5.9. At the same time, support for typeof emulation is not so good (many compilation errors). It would be beneficial for Boost users if Boost used native typeof instead of emulation.

Here is proposed patch:

--- boost/typeof/typeof.hpp.new	2011-08-01 18:46:43.680746049 +0400

+ #	endif
+ #   endif
  #else //unknown compiler
  #   ifndef BOOST_TYPEOF_NATIVE
  #       ifndef BOOST_TYPEOF_EMULATION

Patch committed to trunk

Even with the patch in place, most of the typeof regression tests still fail on the Sun compiler in native mode. http://www.boost.org/development/tests/trunk/developer/typeof.html This must be patched before this change can be integrated to release. I can apply the patch, but I don't have a Sun compiler so I can't write it.

That's expected. Next version of Oracle Solaris Studio C++ compiler 5.12 will handle typeof-related tests more gracefully. There was a minor deviation from common typeof implementation and it has been fixed.

I ran tests with patched boost and patched compiler in-house and got >250 new passes.
