I'm using the macro to do conditional compilation as in
#if _SFR_IO_REG_P(SMPCR)
#define this that
#else
#define this other
#endif

It looks like that all of these macros are written for both C and 
assembler based on the _SFR_ASM_COMPAT switch. I just don't 
understand why the C version of the _SFR_IO_REG_P(SMPCR) macro 
doesn't seem to go through the preprocessor / compiler (at least on 
my system.
