>Description:
Compiling the following with -fno-default-inline

#include <vector>
std::vector<int> v;

leads to:

bellatrix:~/src/tests$ g++-3.3 -c warning.cpp -fno-default-inline
/home/rguenth/ix86/gcc3.3/include/c++/3.3/bits/stl_alloc.h:429: warning: inline function `static void std::__default_alloc_template<__threads, __inst>::deallocate(void*, unsigned int) [with bool __threads = true, int __inst = 0]' used but never defined

while omitting -fno-default-inline or using gcc 3.2 does not produce this bogous warning.
