Does anyone have a macro that will correctly determine when -rdynamic

I saw http://www.mail-archive.com/autoconf@gnu.org/msg15247.html but
there was no definitive response... has anyone come up with something
since then?
I'd prefer to not invoke a test executable, to preserve cross-compiling.
Thanks!
Paul,
I think you're not getting a response because you're asking a lot.
Without testing by running an executable, this can't be determined
behaviorally, so your best bet is some sort of lookup. I would suggest
you write your own macro, where you set the flag based on known system
information, and barring that try some link-time flags and use one that
doesn't generate any errors.
HTH,
Robert
