was busy with a lot of other stuff, so it took me a while to create a port, see attached tarball. The port is far from being "clean", but works so far that I install backtrace_test program, run it, and it crashes for me on i386, see the backtrace below. It works on sparc using gcc-2.95, but there also works the gnustep sudoku for me. $ gdb backtrace_test GNU gdb 6.3 Copyright 2004 Free Software Foundation, Inc.
