The newsgroup comp.sys.ibm.pc.programmer is the old name of the modern
 newsgroup comp.os.msdos.programmer, and the old name has been obsolete
 since September 1990; however, some systems may not have removed the old
 group, or may have removed it but aliased it to the new name.This means
 that some people still think they're posting to
 comp.sys.ibm.pc.programmer even though they're actually posting to
 comp.os.msdos.programmer.

 You can easily verify the non-existence of comp.sys.ibm.pc.programmer by
 reference to the "List of Active Newsgroups" posted to news.groups. It's
