* This is specially useful if you build SDL against a non glibc libc library (such as musl) which
* provides a relatively small default thread stack size (a few kilobytes versus the default 8MB glibc uses).
* Support for this hint is currently available only in the pthread, Windows, and PSP backend.
*
* Instead of this hint, in 2.0.9 and later, you can use
* SDL_CreateThreadWithStackSize(). This hint only works with the classic
* SDL_CreateThread().
