-// linked into a program, this new command line option is available that allows
-// users to load shared objects into the running program.

-// Note that there are no symbols exported by the .o file generated for this
-// .cpp file.  Because of this, a program must link against support.o instead of
-// support.a: otherwise this translation unit will not be included.
