I tried that... this prevents the |b_poll()| symbol from being removed at the final link step but ksh93 then won't be able to find it. It seems the problem is that ksh93 somehow doesn't look inside itself for builtins specified via $ builtin fooname #, e.g. without -f libname (and if I specify $ builtin -f $0 poll # ksh93 comes back and complains about the missing |plugin_version()|). Or short: Your "anchoring" idea works... but we need more work to make it practially useable... ---- Bye, Roland -- __ . . __ (o.\ \/ /.o) roland.ma...@nrubsig.org \__\/\/__/ MPEG specialist, C&&JAVA&&Sun&&Unix programmer /O /==\ O\ TEL +49 641 3992797 (;O/ \/ \O;) _______________________________________________ ast-developers mailing list ast-developers@research.att.com https://mailman.research.att.com/mailman/listinfo/ast-developers
