optional_config.hpp: needs update for Oracle Developer Studio compiler

[Aparna Kumta <aparna.kumta@…>]

Test libs/bimap/test/../example/bimap_and_boost/xpressive.cpp fails with Oracle Developer Studio compiler in -std=c++11 mode as follows:

I also disable SUNPRO, as it seems not to support type_traits correctly
