There my modified patch to directory existence check, this variant more
aestetic,
and in addition - keeps primary UpdateListing() formal specification
untouched
(though to that we may spit, because UpdateListing() currently used only
within directorycacher).
It must be useful, besides directory existence check in compiler options
dialog, because
directory can be renamed outside of design process (imperceptibly to
IDE).
With this correction, IDE bring message about directory non-existence
only with first
attempt to non-existent directory access, and "unit not found" (as
before) with next attempts.
