SCO 5.0.6 binaries stopped working on 5.0.7 MP5

[Brad House]

Anyone have any idea why binaries compiled with GCC 3.3.1
on SCO OpenServer 5.0.6 (w/o execution environment update)
would suddenly stop working on OpenServer 5.0.7 with MP5?

Prior to MP5, everything worked as expected. The only
problem appears to be with dynamically loading shared
objects (dlopen()). The error received is something like
this:

"OpenServer executable cannot load UDK shared object"

Please note I receive this same error when trying to run
on SCO OpenServer 6, so it seems like they backported
this issue from SCO6 ... nice...

If anyone is interested, this is actually a GCC issue.
GCC 3.4.6 on SCO 5.0.7 MP5 also produces the same issue.

The work-around is to run
/udk/usr/ccs/bin/elfmark -t osr5 ${so_file}
to correct the issue, as apparently the shared objects
get marked wrong and 5.0.7MP5 has a sanity check which
prior releases didn't have, preventing the load.
