I'm rather sure either LN_S or as_ln_s used to be overridable at one
point, but doesn't seem to be the case in the current code.  Hmm, I
see ac_cv_prog_LN_S in Autoconf from ten years ago, but that code had
other problems too.

One workaround would be to write a wrapper program called ln which does
exit 1.  :-)  Or, if you somehow need links for something else, fail if
source and target match conf[1-9][0-9]*.* (regex not glob notation)
after disregarding -s, that ought to catch the typical configure tests.

You mean recursive configure invocations?

Thanks,
