If you have any upper case files in the directory you
mount as a filesystem (e.g. -fs c:../stonx_fs).
Although you can navigate the files and they appear
when GEMDOS attempts to load them the Fsfirst/next
native functions fail becuase the converted st name to
unix name is lower case and therefor unable to stat the
file.
Current workaround is to not have upper case files in
any mounted filesystem!
