btw, the "`AC_LINK_IFELSE(..." line is from the autoconf documentation.  It is
the first thing that AC_SEARCH_LIBS does.  It tries to link without any of the
specified libraries first, then it iterates trying to link using each specified
library, stopping when it is successful.

If you didn't recognize that that line was from the documentation, it may be
confusing.
