Windows95 IFS uses absolute paths for all FS lookups.  So does NT.

*ALL* FS lookups.

Same goes for DOS 7.0 shells running INT 21 emulation for programs
running in DOS "Command" on Win95.

If you "cd .." you *don't* get a ".." at the IFSMgr_SetReqHook()
call level.  You get an absolute path with the ".." parsed back.
