    curl_ctype: fix macro redefinition warnings
    
    On MinGW and Cygwin, GCC and clang have been complaining about macro
    redefinitions since 4272a0b0fc49a1ac0ceab5c4a365c9f6ab8bf8e2. Fix this
    by undefining the macros before redefining them as suggested in
    https://github.com/curl/curl/pull/2269.
