Indeed, but this has nothing to do with constructors, as this example shows: 
------------------------------------------------------ 
struct A { 
    int f()  __attribute__ ((deprecated)) {} 
}; 
 
int f()  __attribute__ ((deprecated)) {} 
------------------------------------------------------- 
Compiled with 3.3, we get 
mp/g> ~/bin/gcc-3.3/bin/c++ -c x.cc 
x.cc:2: error: parse error before `{' token 
x.cc:2: error: missing ';' before right brace 
x.cc:5: error: parse error before `{' token 
 
That's not very enlightening. Present mainline tells us more, at least for the 
non-member case: 
mp/g> c++ -c x.cc 
x.cc:2: error: expected function-definition 
x.cc:5: error: attributes are not allowed on a function-definition 
 
So the point is really that attributes are not allowed at function _definitions_ (though it's 
easy to check that they are of course allowed at _declarations_), but that this is only 
properly diagnosed for the non-member case. 
 
W. 
 
PS: A workaround for the original problem is this: 
-------------------- 
struct A { 
    A()  __attribute__ ((deprecated)); 
}; 
 
inline A::A () {} 
---------------------
