# Now we make the adjustments required for OS/2 and everyone
# else :)
#
# First of all, all OS/2 programs have the '.exe' extension.
# Next, we adjust PATH (or what was given to us as PATH) to
# be whitespace separated directories.
# Finally, we try to determine the best flag to use for
# test/[] to look for an executable file. OS/2 just has '-r'
# but with other OSs, we do some funny stuff to check to see
# if test/[] knows about -x, which is the prefered flag.
