But:
      print_backtrace() # alone is enough - thus the name

Here, "struct kprobe" is for some reason not declared.  But
<linux/kprobes.h> is #included from systemtap's runtime.h, so I don't
understand why this should be.  Maybe someone removed CONFIG_KPROBES
from your kernel?  (The translator could emit an assertion for this,
sort of like it does for kretprobes.)
