  Tested x86_64-linux. Pushed to trunk.

We define these with the 'struct' keyword, but the standard uses
'class'. This results in warnings if users try to refer to them using
elaborated type specifiers.

libstdc++-v3/ChangeLog:

	* include/bits/chrono.h (duration, time_point): Change 'struct'
	to 'class'.
