Am I right? I would say, rather, than AST ksh doesn't correctly handle using the compiler's default include path. If you are using any of the compilers included in Debian to build this software, the include path should be set up transparently for you; so for AST ksh to not find these headers means that it's doing something nonstandard. Perhaps you can post a build log? > If ksh source code does not handle multiarch correctly, which document > should I ask upstream to look into in order to understand how multiarch > is implemented in debian?

Those seem like good starting points for discussion, with upstream, yeah. > Am I right this issue is related to multiarch in debian? > Do you have any advices to make my point against the ksh developers?
