 The fix for kern/43128 adds the missing kernel bits for GDB to support
 threaded program debugging.  The other part needed is changes to GDB
 itself.
 
 Attached is a patch that does this, tested on i386 against the GDB 6.5
 sources that are in NetBSD 5.0.  I intend to submit this to the GDB
 project as well but was asked to provide a patch against the GDB rev
 that is currently in NetBSD.
 
 There is a patched mipsnbsd-nat.c as well as common and i386 specific
 files, but I did not make the build file changes for that so that file
 is untested.  I also did not look at any other platforms.  The changes
 should be straightforward using the mips and i386 examples as the
 starting point, but since I have no way to test them I did not want to
 attempt changes for any other targets.
 
 Comments appreciated.
