+Subject: [PATCH] Windows: Use ATOMIC_PTR functions to avoid compiler warnings
+ due to incompatible types
+
+HCRYPTPROV can be casted to pointer without warning but not to size_t.
+Avoids the following warning/error:
+
+../snapshot-master/random.c: In function 'fill_random_bytes_crypt':
+../snapshot-master/include/ruby/atomic.h:246:28: warning: passing argument 1 of 'rbimpl_atomic_size_cas' from incompatible pointer type [-Wincompatible-pointer-types]
