It's EGLBoolean, not EGLenum. Also, no cast is needed between basic types.
typedef int32_t khronos_int32_t;
typedef khronos_int32_t EGLint;
typedef unsigned int EGLBoolean;
The types are equivalent on 32-bit and 64-bit, so I could have just
made eglWaitSyncKHR be an alias of eglWaitSync and it would work, but
I wanted to document this in the code.
