Problem building epics base under cygwin

["Michael D. Westfall" <mikew@lanl.gov>]

Just installed Cygwin on my laptop, then downloaded epics base 3.14.11

Running 'make' it fails while building ca.lib with  "undefined reference
to 'typeinfo for epicsTimerNotify' while linking several object files
including tcpSendWatchdog.o, tcpRecvWatchdog.o and
repeaterSubscriberTimer.o


Anybody else have this problem?
