Ah! Now I understand what Tim and others are talking about. If I link the C
program with -lieee, I get
1e+200 inf 0 Success 34
1e-200 0 0 Success 34
So my question now is: What do I do to tell Python to compile with -lieee?
In the source tree there are several places that mention this, but none of
which looks like meant for hand editing. The lines in ./pyconfig.h
/* Define if you have the ieee library (-lieee). */
/* #undef HAVE_LIBIEEE */
looks like it. But since it's already commented out, does that mean
HAVE_LIBIEEE is already defined?
