Hi Beman,

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.

You probably want to check __GLIBC__, __GLIBC__MINOR__ and maybe
__GNUC_PATCHLEVEL__ instead.

The C++0x library status is shown at
http://gcc.gnu.org/onlinedocs/libstdc++/manual/status.html#manual.intro.status.standard.200x

However, that shows the status for the subversion trunk, to get the
info you want you'd need to check the docbook xml source in each GCC
release to see when the status changed for each item.  It might make
sense to add an extra column to the table showing the release in which
the status changed to Y.
