This is a hack to override constness of struct members however, with modern compiler like clang with fortified glibc ( 2.40+ ) headers this runs into compiler errors

Therefore take this out, instead cast away the 'const' qualifier where needed ( equilly dangerous ) however limited to just this file instead of apply to all headers including system headers
