Hum, It is surprising if you were the first person to find this, if it is indeed wrong. I see why it would be better to work the other way. Do you know if this...

Jefferson, A general note, compiling with the -S switch to gcc will generate an assembly file of the C code. Reading through the assembly code will provide an...
Good fix from John, although I think it was supposed to address Frank since I didn't write the code for which I'm posting a fix :) I liked the "-S" option...
Hi John Many thanks for the reference files. I have managed to sort of get my test project to compile and link after checking through it. I will have to try...
