+	* src/buffer.c (struct zip_magic): Use char arrays, not pointers.
+	The unsigned char * pointer ran afoul of pedantic C compilers, and
+	we didn't need pointers anyway.  Put the size field before the
+	data to avoid unnecessary padding.  All uses changed.
+	(magic) Make it const, since it doesn't change.  All used changed.
