This sounds odd, as there is no variable a or _a in file2.c, and if you can see a variable in one file you should be able to see if with the same name in another file. Anyways, I think I already answered this with my first message when I pointed you at ASM_OUTPUT_* and ASM_GENERATE_INTERNAL_LABEL etc. If you compile with -g -S, and look at the assembly language, you will see that "_a" is being used in the debug info someplace for the variable name where "a" should be used instead. "_a" is correct for the variable address, but not the variable name. So you will have to step through your gcc port to figure out why the "_a" is incorrectly printed, and most likely it is a bug in one of the macros I have mentioned. Take a look at a port that handles this correctly to see what they do differently to make this work. Jim
