SDCC support?

As I understand, support for SDCC COMPILER is not?
I get this output: 

```
sdcc -lstm8 -mstm8 --out-fmt-ihx   main.c
In file included from stm8sduino.h:56,
                 from main.c:3:
stm8s.h:88:3: error: #error "Unsupported Compiler!"
stm8s.h:2733:25: fatal error: intrinsics.h: No such file or directory
compilation terminated.
make: *** [main.ihx] Error 1
```
