Would you please change the formatting so that the { } are on lines by 
themselves (see the surrounding code for examples)?

I think it's better to store the error code in a new local volatile int 
variable, so that both old and new error code are accessible.  The old 
error code seems quite valuable, too.

Thanks,
Florian
