Are you sure? The Raisonance C compiler for ST7/STM8 appears to expect the 
interrupt or trap keywords to follow the function parameters, like SDCC. 
See pages 43-44 here:

You might also want to double check that you have the current version of 
the STM8-SPL. From the link you provided, I downloaded STSW-STM8069 
version 2.2.0. It appears to provide compiler specific implementations of 
a macro named INTERRUPT_HANDLER that takes two parameters: a function name 
and a vector number. The macro forms a function declaration with interrupt 
keyword either at the beginning or end of the declartion, as appropriate 
for the detected compiler.
