But we need someone to test it.
It may well be good enough. I cannot test it because (a) I have no access to any of the affected machines, and (b) for other reasons, libstdc++ cannot currently migrate away from autoconf 2.13. (See the discussion at <http://gcc.gnu.org/ml/gcc-patches/2001-05/msg01986.html>; suggestions would be appreciated.) If you can show me a simple test script which determines if $LINENO works, I can ask the people experiencing the problem to tell me what the problem shells make of it. zw
