_AS_PATH_WALK is used in many places, some of which allow the
configure.ac author to override the PATH argument; for example, try
AC_CHECK_PROG([FOO], [foo], [], [], [$bar])
with unset $bar for fun.
OK? (even if it makes `configure' scripts somewhat longer still ;-)
Cheers,
Ralf
* lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not forget to reset
IFS even in case of empty `$PATH'.
