It doesn't appear that the source for ifcomty is present in the directory. There are other references that imply some things were moved to ifwinty related to automation.
!dec$objcomment lib: "ifauto.lib"
ifcomty module is present however. Has my source file been accidently deleted by chance or is this actually missing in the original install?
Some of the sources define multiple modules. I am not at one of my IVF computers right now or I'd check for you.
