Nope: RTFM (although, IIRC it isn't very clear on this issue and I had to
	fix the make.y (or was it make.l) on one version in order for make
	not to barf at the second ':').

In SVSY make, with:

O	= objdir
OBJS	= $O/file1.o $O/file2.o

${OBJS}: $${F:.o=.c}
	rules

is equivalent to:

$O/file1.o: file1.c
	rules

$O/file2.o: file2.c
	rules

and is useful for multi-architecture makefiles.
(I would usually add dependency against all the local .h files, but
not the system ones.)
