+Subject: [PATCH] Include <cstdint> for uintptr_t
+
+GCC 15 adheres more strictly to the standard about which type is defined
+in which header. As such, uintptr_t is no longer available unless
+cstdint is included.
+
+Add #include <cstdint> in the files that use uintptr_t.
+
+Note that in masm, stdint.h is included instead of cstdint, so leave
+those alone.
