Thanks for your response, yeah I use a dumb email address for lists to 
avoid spam.

Could I just go into the Makefile and add the flag? or is it a configure 
option? Where would this directive normally be?

I'd be happy to change to 6.8 but since I'm using it for cross compiling 
I need to ensure that it will work with the m68hc11.... also this is my 
first experience setting up a toolchain, so I'm trying to be 
conservative with what I try (since i'm not sure about what might work 
and don't want to get in over my head).

If anyone know of a toolchain that works with a newer version of GDB 
please let me know.

Thanks again,

Nathan
