And SDCC should tell you:

void f(void) __sdcccall(0);

void f(void)
{
}

philipp@notebook6:/tmp$ ~/sdcc-trunk/sdcc/bin/sdcc -mstm8 test.c
test.c:3: error 98: conflict with previous declaration of 'f' for 
attribute 'type' at test.c:1
from type 'void function ( ) __sdcccall(1) fixed'
   to type 'void function ( ) fixed'

Actually, the error message is could be better here, as it should have 
the __sdccall(1) explicit, and the other one implicit, like in the code, 
but at least there is an error.
