comptability with previous linker behaviour. Whilst strictly
speaking it is not a failure to encounter unresolved symbols at
link time - the symbol *might* be available at load time - it is
nevertheless necessary for the correct execution of the autoconf
package. (It needs to be able to detect functions that are not
provided by the host OS). Since this package is used by lots of
projects, maintaining the old linker behaviour is important. */
