atomic_load/atomic_compare_exchange_weak does not work on structures

The following code gives a compilation error using cosmocc (GCC) 11.2.0, while the code compiles without any error using GCC/Clang.

hello.c: In function ‘main’:
hello.c:11:3: error: operand type ‘_Atomic atomic_ant *’ {aka ‘_Atomic ant *’} is incompatible with argument 1 of ‘__atomic_load_n’
