This test also fails on MacOS X 10.1.

I had a more detailed look at the C standards.  C99 specifies that the
output should be "0", but C89 was not so clear.  I still think "0" is
the right answer for C89, but the standard is not entirely conclusive on
this issue.  Maybe my initial diagnosis that outputting "" was a bug was
a bit too quick.  Even if that behaviour is a mistake, if two different
C implementations have made the same mistake, then it is an area of C89
that we should not rely on.  In which case adding another .exp would be
the right solution.

I've asked about it on comp.std.c.  Let's wait a few days and see what
response we get there.

On a related note, the tests/general/string_to_float test also fails on
MacOS X: it doesn't output a minus sign for -0.0.
