yo -

i'm joining the party late, but i saw this message in the archive.
sorry for the copy/paste...

Yes, ELF files have this. in the dynamic section there is an entry of
type DT_DEBUG. that holds a pointer to the r_debug structure, which
holds a pointer to the link_map. the link_map structure is a linked
list of all the shared objects currently loaded.

the r_debug structure has the stuff you'll need to get runtime dynamic
linking working.

i'm interesting in helping out. where are the linux people working on
this hanging out? don't want to re-write anything anyone else is
already hacking on...
