Comment:

 This particular configtest has the outward appearance of being broken
 rather than of failing so I was assuming the build had failed. Autoconf
 manages to handle failing tests in a rather less alarming way, printing
 just yes or no, so if this is just a no it'd be nice if it looked less
 fatal. It seems numpy may have gone on to build fully. I just tried to
 install it and run the tests. (Is there a way to run the test cases from
 the build directory without first installing?)

 From the test cases I get one failure and some warnings. The warnings are:
   Warning: overflow encountered in ldexp
   Warning: invalid value encountered in power

 The failure is:
 FAIL: test_special_values (test_umath_complex.TestClog)
 ----------------------------------------------------------------------
