I don't think that flies so well. The bugs we hit in older
compilers were location lists that looked fine but were incorrect

those location lists as bad.
Too bad. OK, then let's gather some data about compiler versions and
architectures. If we find a reasonable and documentable dividing line
between working and not working, then we can make systemtap assume the
former. (We could retain a discreet switch such as an environment
variable to activate the prologue code for people stuck with
non-working systems.)
