I'll point out that for the case at hand, a configure test, code readability is probably not a very important goal. As Ken points out, the configure check failed before, but for the wrong reason - NULL wasn't defined. Now it'll fail for the right reason - the function doesn't exist on MacOS X. The compiler warning during the configure check is only apparent in the configure log, which is probably why the reason for this failing was missed for so long. --Juan
