Apache::Symbol::undef wants to clobber the CV regardless.  it was a
special version of pp_undef to avoid the old mandatory warning of constant
subroutine being re-defined.
cv_const_sv() is handy to check if a subroutine has been constant
folded.  i didn't notice this breakage, both are referenced in
Apache/, which builds fine, but is not used by the 'core'.  now i
notice mod_perl skips the modules/symbol test because it fails to load.
it would be nice if these could be made public again.
