Comment (by howarth@…):

 Using  --enable-libstdccxx-time without arguments doesn't do anything
 because that defaults to 'no'.[[BR]]
 Furthermore, using  --enable-libstdccxx-time=yes won't work because the
 configure tests for nanosleep [[BR]]
 support in libstdc++-v3/configure ultimately fails on the test...[[BR]]
