From: Christopher Faylor <me@cgf.cx>

Subject: * dir.cc (readdir_workdir): Only fill out d_ino when linked into
 older app. * include/cygwin/version.h: Bump api minor number to 147,
 reflecting obsolescence of d_ino. (CYGWIN_VERSION_USER_API_VERSION_COMBINED):
 New convenience macro. (CYGWIN_VERSION_CHECK_FOR_NEEDS_D_INO): New
 convenience macro.
