Yep, I understand that.  But, now you have exposed another Autoconf shell
variable, which the user is expected to override by invoking

  path/to/configure LN_S='cp -p' ...

for a situation which may be peculiar to a MinGW GCC build under Cygwin.

If you are comfortable with that as a standard Autoconf feature, and you
document it properly, then I don't have a problem with it.
