-Winline: function body not available

[Martin Sebor]

Could someone help me understand what's causing the following
warning so that I can silence it? Gcc 3.4.3 emits it for an
implicitly inline one-line definition of the function (ctor,
actually, see below), so I'm not sure what the "function body
not available" bit is supposed to mean. The base ctor is also
a one liner defined completely inline. The base derives from
two other class, one of whose ctor is outlined and the other
is trivial (i.e., compiler generated).

I've searched Bugzilla but couldn't find anything relevant.

Thanks
Martin
