[Bug c++/14510] New: Bogus conflicting declaration error message

["schmid at snake dot iap dot physik dot tu-darmstadt dot de" <gcc-bugzilla at gcc dot gnu dot org>]

I believe that there is no second declaration of the struct t_bind in the 
following example. Therefore a rejection of the source code is not warranted. I 
guess this is a regression. This example is taken from the current Ace 
distribution.
