I'm attaching the upstream reply (from [1]): The configtest are, as the name suggests, attempts to compile some simple C code with different sizes for built-in types, as I understand it. Maybe some other checks, not sure about that. In the end a configuration should be found that compiles without problems. So it's allowed to fail, but not to throw an error that stops the build process. [1] http://projects.scipy.org/numpy/ticket/1526 so the purpose of _configtest.c is to actually fail, in order to identify the config options set to use: the failures seen in the build log are "under control". That said, I'm closing this bug.
