UNC support:		- 1997/10/25 ska
====================================
Fully-qualified filenames maybe written in UNC notation, but pre-DOS7
won't accept such filename nor does the DOS box itself supports UNC
completely: If one starts a program from a shared directory via its UNC
notation the current used current working path is _not_ the UNC path,
but the current working path of the DOS drive. This will erroreously
make the program believe its program files reside at a totally different
location. Though, argv[0] contains the UNC path of the program.
