I have investigated further and found the problem, but am unsure on how
to fix it. There 2 assembler files for containing some code related to interrupts. 
The 2 files are linked in when linking directly with all the files, but are not linked 
in from the library. All the other _read, _write etc modules are linked in from the 
library. The linker does not complain about any missing references when the 
assembly code is not linked in. I haved added the "used" attribute to the 
interrupt service routine, but the assembler calling this routine is still not linked 
in from the library.
