Hi!
While trying to distcheck CVS Coreutils with CVS Autoconf and
CVS Automake I've seen this:
gcc -g -O2 -o tail tail.o ../lib/libfetish.a ../lib/libfetish.a -lm -lrt none
required
gcc: none: No such file or directory
gcc: required: No such file or directory
[config.log]
...
configure:33651: checking for library containing nanosleep
configure:33681: gcc -o conftest -g -O2 conftest.c >&5
configure:33687: $? = 0
configure:33691: test -z
|| test ! -s conftest.err
configure:33694: $? = 0
configure:33697: test -s conftest
configure:33700: $? = 0
configure:33770: result: none required
...
[src/Makefile]
...
LIB_NANOSLEEP = none required
...
nanosec_libs = \
$(LDADD) $(FESETROUND_LIBM) $(POW_LIB) $(LIB_CLOCK_GETTIME) $(LIB_NANOSLEEP)
...
sleep_LDADD = $(nanosec_libs)
tail_LDADD = $(nanosec_libs)
...
configure protects its LIBS setting with
test "$ac_cv_search_nanosleep" = "none required" || LIBS="$ac_cv_search_nanosleep
$LIBS"
maybe jm_FUNC_NANOSLEEP should protect it's LIB_NANOSLEEP
setting similarly.

* nanosleep.m4 (jm_FUNC_NANOSLEEP): Do not fill LIB_NANOSLEEP
with $ac_cv_search_nanosleep if it's "none required".
