Well, half an hour after posting my question, I was poking at the mingw 
site I found a link to a tutorial that mentined the -lXXX and libXXX.a 
naming convention.  Sure enough, when I applied the correct naming 
scheme the linker found the library.  I now have other issues and 
questions, but I want to tinker a bit more before coming out more questions.
