Since we would also get the problem if we set CURLPROTO_FOO *only*, the check would probably have to be:
#if SIZEOF_LONG < SIZEOF_CURL_OFF_T if(allowed_protocols&CURLPROTO_EXTENDED_FLAG) return ERROR; #endif... but, this also then assumes that it will actually read the *correct* 4 bytes from the 8 that were pushed on the stack and I don't think it is guaranteed in the C language so there's a risk that the check won't work.
