It's actually "exit" filtered through the -wrap linker option.
The reference is supposed to be there, and the definition too.
I don't see this with LAST_UPDATED at "Fri Mar 21 13:18:25 GMT 2003".
Plausible causes: dejagnu harness bug, gcc testsuite bug, some
gcc sysroot bug, ld bug.  Anything changing in those areas is
suspected.

I assume you updated the whole tree, including binutils and
DejaGNU in uberbaum at the same time?

You probably see this for all targets with
 set_board_info needs_status_wrapper  1
in dejagnu/baseboards/<BOARDNAME>.exp, for example arm-sim.exp.

Sigh.  Could just the guilty party please raise a hand?
