random numbers. It is used to generate certain symbol names
that have to be different in every compiled file. It is also used to
place unique stamps in coverage data files and the object files that
produce them. You can use the @option{-frandom-seed} option to produce
reproducibly identical object files.
The @var{string} should be different for every file you compile.
