Log message:
        Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
        or CFLAGS=-O5.  In that case, the linker has a relaxed view of
        fatal errors, and AC_CHECK_LIB causes it to include libraries even
        when they don't exist.
        
        * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
        not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
        need it.
        
        * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
        version with the version used by fileutils 4.1, except use
        AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
        we don't need it.
        
        * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
