Thanks Fred,

I have another couple of questions that you might be able to answer:

1) what is the difference between the lib\arm\interwork and 
lib\thumb\interwork libraries ?

2) if I specify -mthumb-interwork to the compiler/assembler for a 
source file, what does this do to functions in that file e.g. does it 
add extra code to it or mark them as inter-arm/thumb calls ?

Many thanks
Dave
