We substitute H_GCC_ATTRIBUTE to any occurence of __attribute__ and disable its function with non gcc, non clang compilers. We use a H_ macro so as to not pollute users' namespaces. On windows build without c4201 so as to allow anonymous struct. This shows hammer is not C99 compliant but rather C11.
