This macro is not useful for determining whether a particular feature is

supported by the version of libstdc++ you are using. The date of a release

might be after a feature was added to the development trunk, but the
|

release could be from an older branch. For example, in the 5.4.0 release
|
||||
the macro has the value 20160603 which is greater than the 20160427 value

of the macro in the 6.1.0 release, but there are features supported in the
|

6.1.0 release that are not supported in 5.4.0 release.

The macro value might be a date after a feature was added to the

<code class="literal">20160603</code> which is greater than the

You also can't test for the the exact values listed below to try and

identify a release, because a snapshot taken from the gcc-5-branch on

You also can't test for the the exact values listed below to try and

identify a release, because a snapshot taken from the gcc-5-branch on

2016-04-27 would have the same value for the macro as the 6.1.0 release

despite being a different version.
|

Many GNU/Linux distributions build their GCC packages from snapshots, so

the macro can have dates that doesn't correspond to official releases.
