Fixed in trunk as part of r9998.

I see this problem only manifests when a fairly minimal mapserver is build. A maximal mapserver will pull in some include files that pull in errno.h. I'm not sure exactly what options make the key difference. But the good thing is that mapserver 5.6.3 is likely not broken for most people.

Fixed also in 5.6 branch (r9999). The only released mapserver with this problem is 5.6.3.
