I've run across a problem with GNU make and Imake.
The command sequence in imake is (typical for imake with sub-directories):
	for i in list_of_directories ;\
	do \
	    (cd $$i ; echo Making all in $$i ...; \
	    $(MAKE) $(MFLAGS) all ); \
	done
This command sequence is executed via '/bin/sh -c command_sequence'.
The problem is that if a non-last (from list_of_directories) sub-make
aborts with an error, the sub-make reports the error but the 1st level
make does not quit.  The fix is to pass the -e flag to the shell which
says 'exit immediately if a command exits with a nonzero exit status'.
This additional flag to the shell should probably be optional based on
-k being given to make (-k given to make should imply no -e to the shell).

Note that Sun's version of make does pass -e to the shell, though I
haven't verified that passing -k to make turns off -e to the shell.
