The commands for compiling and linking depend on the operating
system where you are building the examples.  "configure" performs
a number of tests to determine what those commands are.  If you
run "configure" and then "make", you can see the exact commands
used to compile and link the code.  Below is what "make" prints
on my system; on yours the commands will probably be different.
