building base on cygwin1.7

["Pete R. Jemian" <prjemian@gmail.com>]

Anyone have experience yet with building EPICS base on cygwin 1.7?  My 
C++ is not good enough to resolve this problem.

EPICS_HOST_ARCH = cygwin-x86
situation: building EPICS base 3.14.11
host: cygwin 1.7 on Windows 7 Ultimate 64-bit OS
error: undefined reference to `typeinfo for epicsTimerNotify'

fails: Win7-64bit / cygwin1.7
succeeds: Win7-64bit / cygwin1.5
succeeds: Win7-32bit / cygwin1.5
not tested yet: Win7-32bit / cygwin1.7

The build fails
