PS1, Line 56: {
You can put a

#if !defined(__PRE_RAM__)
  dead_code("Cannot strdup() in pre-RAM environments")
#endif

here, then you'll guarantee with a link-time assertion that calls to this will get optimized out. (I guess the undefined reference to malloc would do the same, but this makes the intent more explicit.)
