I've since created more cpp files for each of the header files and added
those arguments and now I get:
[cassidy@txl thesisCode]$ make
g++ -o timsProgram OutputStream.o FilterOutputStream.o
BufferedOutputStream.o Throwable.o BufferedWriter.o Hashtable.o MainEntry.o
MonitorDataLINUX.o TimDynamic.o TimMonitor.o TimObject.o TimString.o

txl::io::BufferedOutputStream' follow

I don't know why - but the linker seems to be having a problem with the
constructor and destructor of BufferedOutputStream - I'm now explicitly
writing the implementation of the default constructor and the destructor in
the implementation/source file of BufferedOutputStream and
FilterOutputStream (which BufferedOutputStream extends).
