>Description:
A makefile containing the following (this is not the complete makefile...)
all: ${TOP_LIBDIR}/libafsrpc.a
libafsrpc.a: ${LIBOBJS}
$(RM) -f $@
$(AR) crv $@ ${LIBOBJS}
$(RANLIB) $@
case "${SYS_NAME}" in \
rs_aix*) \
$(AR) crv $@ ../sys/afsl.exp;; \
esac
${TOP_LIBDIR}/libafsrpc.a: libafsrpc.a
${INSTALL} $? $@
has the following behaavior if make is invoked when the library is up to date
(this is a subset of the make -d lmv output):

Not enough file names
*** Error code 1
The obvious work around is to use $< or $> in the rule instead of $?, but that
isn't workable in this case since some older makes don't impliment those.
I can't be sure that nothing else changed, but I believe that this problem did
not affect my FreeBSD 4.4 system
>How-To-Repeat:
I tried to produce a minimal makefile that triggered the problem, but
I was unable to come up with something simple that did not work. The actual
makefile that triggers the problem comes from openafs. A version that otherwise
compiles on freebsd is available here:
http://grand.central.org/dl/openafs/1.3.1/openafs-1.3.1-src.tar.bz2
