use of cast expressions as lvalues is deprecated

[Massimiliano Cialdi <cialdi@xxxxxxxxx>]

I use h8300-elf gcc 3.4.3

If I write the following:

void *qmemcpy(void *dst, register const void *src, register long len)
{
  register char *d;
  for (d = dst; --len >= 0; *d++ = *((char*)src)++) ; // warning here
  return dst;
}


I obtain:
qmemcpy.c: In function `qmemcpy':
qmemcpy.c(7) : warning: use of cast expressions as lvalues is deprecated


There exist a way to avoid the use of another variable to resolve this
warning?

thanks
