discussed some time ago.

While trying a new Linux installation with the latest tools, the same 
happened here. The error disappeared after removing the cases 
UART_SETSTATUS and UART_GETSTATUS using "#if 0" and "#endif". Over the 
years it happened several times that GCC fails to optimize large 
switch/case constructs. If you need the UART_..STATUS functions, you may 
try to put them in seperate functions, which are called from the switch 
case.
