This code has been modified a bit lately.

The CVS copy of reg_memcpy.S should be:

#include "setarch.h"

#include "defines.h"

        ; dst A0
        ; src A1
        ; len A2
        .global ___reg_memcpy
___reg_memcpy:

        MOVP    A0P,A3P ; keep copy of result
        ADDP    A2P,A0P ; point to end of dst
        ADDP    A2P,A1P ; point to end of src
        CMPP    A0P,A3P ; see if anything to do
        beq     quit

loop:
#ifdef __NORMAL_MODE__
        sub     #1,A1P          ; point to byte
#else
        subs    #1,A1P          ; point to byte
#endif
        mov.b   @A1P,A2L        ; get byte
        mov.b   A2L,@-A0P       ; save byte
        CMPP    A0P,A3P         ; at the front again ?
        bne     loop

        ; return with A0 pointing to dst
quit:   rts

Notice that "setarch.h" is included.  It has the defines you are talking about.

I can't help you immediately with the error you are seeing as I don't have an 
h8300-hms build handy.  Perhaps Dhananjay can be of some assistance here.
