assert.h: document SPDK_STATIC_ASSERT

Browse Source

needs to be on the definition under the #else branch.

* Compatibility wrapper for static_assert.

* This won't actually enforce the condition when compiled with an environment that doesn't support
* C11 static_assert; it is only intended to allow end users with old compilers to build the package.
*
* Developers should use a recent compiler that provides static_assert.
