The following seems to only not work in GCC (neither MinGW nor native
GCC), but it compiles fine in MSVC.
```
template
struct A
{
int numElements;
T* elements;
};
template
class B : public A
{
B(int newNumElements)
{
numElements = newNumElements; // This fails with error.

According to docs, the order is unspecified, but running them in
reverse order would be more logical.
When libstdc++ is built, it can either provide its own implementation
of __cxa_thread_atexit or use one from the host environment.
When libstdc++ is cross compiled, the configure script doesn't d
Within winpthreads, a native posix thread is a thread that has
been created via pthread_create.
Previously, pthread key destructors were executed immediately when
the thread exits, for native posix threads. For non-posix native
threads (i.e. threads created via some other API than pthreads),
