I've just discovered a minor incompatibility between rc and sh:
sh -ce foo # execute foo and exit on any error
rc -ce foo # execute e with an argument of foo
rc is behaving according to the manual page, so this is not a bug,
however, I wonder if the behaviour should be changed to follow that of
sh?
I came across this using make on our new SGI machine -- it executes
commands with $SHELL -ce ... and I had forgotten to explicity set SHELL
to sh within the Makefile.
Alan.

It absolutely and definitely should be so changed.
OK,
John.

I've reported this to Byron more than a year ago. This was
his reply.

This is a stupid bug in make if you ask me. I encountered the same
problem with SCO Unix, and fixed make on our base system tape to do the
right thing by flipping -ce to -ec.
