>Description: 

	When a makefile has a target with embedded shell comands that start
	with @, it will not execute them properly, actually seeking a
command that begins with '@' (say @for) rather than just not echoing the
command in question.

>How-To-Repeat: 

A makefile fragment of the form

# a very simple makefile...
pmake::
	@for flag in ${MAKEFLAGS} ''; do \
	case "$$flag" in *=*) ;; *[i]*) set +e;; esac; done; \
	@for i in develhdrs/local; do if [ -d $(DESTDIR)$$i ]; then \
	set +x; else (set -x; $(MKDIRHIER) $(DESTDIR)$$i); fi \
	done
	@echo 'make started.'
	@for i in *.c; do \
	        echo $i; \
	done
	cc -I. -c *.c
	cd lst.lib; cc -I.. -c *.c
	cc *.o lst.lib/*.o -o pmake
	@echo 'make completed.' 

will cause an error like the following -

@for: not found
*** Error code 2
 
   

>Fix: 
	
	Unknown at this stage - looks like a perverse make bug
