    @@ Commit message
         suite for the socket and timer handling code. This is all based on TAP
         and driven by our existing Test::More infrastructure.
     
    +    This commit is a replay of 1443b6c0e, which was reverted due to
    +    buildfarm failures. Compared with that, this version protects the build
    +    targets in the Makefile with a with_libcurl conditional, and it tweaks
    +    the code style in 001_oauth.pl.
