What with the multitude of versions of High-C for IBM RT under AOS I
would like to offer the following that allows one to have any and all
versions installed and usable at the same time.  One needs to create a
few directories in /usr/lib to hold the different passes of the
different versions of High-C.

Try the following:

# cd /usr/lib
# mkdir hc2.1d hc2.1n hc2.1s

After creating these directories put the passes of the different
versions into the appropriately named directories.  Create a shell
script in /bin for each of different versions:

# cd /bin
# mv hc hc.real
# echo 'exec hc.real -B/usr/lib/hc2.1d/ $@' > hc2.1d
# echo 'exec hc.real -B/usr/lib/hc2.1n/ $@' > hc2.1n
# echo 'exec hc.real -B/usr/lib/hc2.1s/ $@' > hc2.1s
# chmod 755 hc2.1?

Then create a sym link to your favorite flavor of High-C:

# ln -s hc2.1n hc

Now one can use the appropriate version depending on what bug your
code tickles in the High-C compiler. :-)
