+Use extern "C" instead of __BEGIN_DECL/__END_DECL macros
+these macros are defined in sys/cdefs.h for glibc and this header is not available on all libc
+
+anyway they defined like below
+
+#ifdef __cplusplus
+# define __BEGIN_DECLS extern "C" {
+# define __END_DECLS }
+#else
+# define __BEGIN_DECLS /* empty */
+# define __END_DECLS /* empty */
+#endif
+
+__THROW macro is also not available on musl, defined thusly
+
