Yup, that looks relevant. The configure test fails to do what it was trying to do because it redefines a macro, which is usually accepted with a warning, but it requests that warnings be turned into errors by using -Werror. 

autoconf 2.71 caused this problem to appear. autoconf 2.69 didn't first define _DARWIN_C_SOURCE to 1 but autoconf 2.71 does.

The autoconf 2.70 release notes specifically state that "Running configure tests with warnings promoted to errors is not supported."

Please file a bug report.
