 Specify additional source files to appear in the compile line
 following the main test file.
 If the directive includes the optional @samp{@{ @var{selector} @}}
 then the additional sources are only added if the target system
 matches the @var{selector}.
-Additional sources are generally used only in @samp{link} and @samp{run}
-tests; they are reported as unsupported and discarded in other kinds of
-tests that direct the compiler to output to a single file.
