Something I forgot in my AC_LN_S patch

[Tim Van Holder]

You may have wondered why my AC_LN_S sets ac_ln_s...

(Note: Should CONFIG_LINKS() AC_REQUIRE AC_PROG_LN_S()?)

Well, here's why:

2001-01-24      Tim Van Holder <address@hidden>

        * acgeneral.m4 (AC_INIT_DEFAULTS): ac_ln_s: new variable;
        default to 'ln -s'.
        (_AC_OUTPUT_CONFIG_STATUS): Propagate $ac_ln_s to config.status.
        (_AC_OUTPUT_LINKS): Use $ac_ln_s, not 'ln -s'.
