I screwed that up, didn't I?
This is a result of the newlib change to sys/time.h. It has been
updated to the latest stuff from FreeBSD in March.
Before, we had a <cygwin/sys_time.h> header which defines futimes and
lutimes. Since these symbols are now defined in newlib's new sys/time.h,
I concluded razor-sharp, that we don't need the cygwin-specific
Unfortunately I missed the fact that this file also includes <sys/select.h>.

I applied a patch. A new version of Cygwin has to wait until I'm back
from vaca, sorry.
