commit 8719f4fcc1685a320e648166cf6720c3e33f0434
Author: Florian Dold <address@hidden>
AuthorDate: Tue Apr 30 20:46:17 2019 +0200

    Make gnurl and curl mutually exclusive.
    
    This prevents issues when both curl and gnurl are available, but one of
    them is outdated.
    
    To get curl.h, we also now just include gnunet_curl_lib.h instead of
    writing the preprocessor conditionals manually.
    
    Fixes #5707
