Use GetLogicalProcessorInformation to get the number of physical processors on Cygwin. GetLogicalProcessorInformation is already used in native Windows.  Allow it to be used in Cygwin as well.  It requires SYSTEM_LOGICAL_PROCESSOR_INFORMATION to be defined in the header file which seems to need a relatively up-to-date version of Cygwin.
