Well, this should be using tempfile anyways.

The presence of these functions should have been detected by the
configuration process of numpy. HAVE_FREXPF and HAVE_LDEXPF would have
been #define'd if we had detected them correctly. It is possible that
our configuration process for this does not work correctly with VS
2008. From a clean checkout, can you please do the build again and
copy-and-paste everything printed to the terminal?
