something you can do is put the call to DosQFSAttach in a segment that is
marked as "LOADONCALL" in the .def file.  then, you only call your IsHpfs()
call when you have already checked the os/2 version number.  In that way, you
avoid the fault on the load of the program because it won't load and fixup the
code segment with the unsupported API call (for v1.1).  When you do call it,
os/2 will load the segment and perform the fixups then instead of at program
startup time with a "PRELOAD" (the default) segment attribute.

Hope this helps.
