I've only done a quick scan but I see an immediate potential trouble 
spot.  You have no actual interrupt function.
You placed a macro of inline assembly at the beginning of what you expect 
to be your interrupt function.

That might work, although I certainly wouldn't place any great expectations 
that it would without inspecting the actually output assembly code.  Even 
if it did work I wouldn't place any great faith in it continuing to work as 
either the compiler or other code is changed.

My first advice build a proper interrupt wrapper (and yes do it in 
assembly),  It's not difficult and that way you will know that it is 
correct.  I'm sounding a bit like a broken record but there is an example 
of such a wrapper in the newlib-lpc code.

The other option would be to upgrade the compiler to get a working 
interrupt keyword (me I don't trust compilers to get this 'right', but 
that's just me).
