Shouldn't the test for use_clipboard_aurax11==1 be enough?

This may look a bit weird, but this is side effect of
win_aura not using clipboard_aura.cc. 

[sky, 2013/12/13 17:55:31]

Shouldn't the test then be os==win and use_aura or use_clipboard_aurax11?

If you ask my preference, I prefer not to include "for all" case
and include each file for each configuration. That is far less confusing IMO.
