Description: Test for old curl by version rather than with #ifndef
 As of curl 7.37.1, CURLOPT_READDATA and CURLOPT_WRITEDATA are enums rather
 than #defines and the old names are #defines instead; testing for them with
 #ifndef results in #define loops.  Use a version test instead to find out
 whether we need compatibility definitions.
