 I got 73 warnings of the type
 {{{
 :info:build ./gpsd_config.h:303:13: warning: redefinition of typedef
 'clockid_t' is a C11 feature [-Wtypedef-redefinition]
 :info:build typedef int clockid_t;

 }}}
 all resulting from invocations of `/opt/local/bin/clang-mp-3.4`.

 Then I got this:
 {{{

 }}}

 I'm convinced that there are two problems here: the first is that
 `clockid_t` should not be redefined, the second is that SCons does not
 choose the desired compiler.
 I don't know SCons, but I read that it does not automatically obey `CC`,
 `CXX`, ... environment variables, so probably both problems need to be
 solved upstream.
