# Under non-Linux, the link format "elf" forces a file name extension of .elf.
|
|
# While this can be prevented by the NOEXTENSION link option, the resulting
|
|
# file without extension will not be detected by the "exist" below, so a "clean"
|
|
# leaves the file in place. Under Linux this detection works properly.
|
|
# Watcom ought to have a internal (=platform independent) command to detect
|
|
# the presence of such a file. E.g. %exist alllowing wildcards.
