//  __GNUC_PATCHLEVEL__ at the suggestion of Jonathan Wakely, one of the stdlibc++
//  developers. He also commented:
//
//       "I'm not sure how useful __GLIBCXX__ is for your purposes, for instance in
//       GCC 4.2.4 it is set to 20080519 but in GCC 4.3.0 it is set to 20080305.
//       Although 4.3.0 was released earlier than 4.2.4, it has better C++0x support
//       than any release in the 4.2 series."
