* ns32k-tdep.c: #include "frame.h"

* config/ns32k/tm-umax.h (FRAME_FIND_SAVED_REGS): Restore.  It
appears to have been inadvertantly removed sometime in May 1999.

* Revert 2000-11-09 changes where shared library objects were
moved from NATDEPFILES to TDEPFILES on NetBSD targets.  While
we'd like to be able to debug dynamically linked executables,
this makes it impossible to build a cross debugger on a many
hosts.

* config/i386/nbsd.mt: Remove solib.o, solib-svr4.o from TDEPFILES.
* config/i386/nbsdelf.mt: Likewise.
* config/m68k/nbsd.mt: Likewise.
* config/ns32k/nbsd.mt: Likewise.
* config/powerpc/nbsd.mt: Likewise.
* config/sparc/nbsd.mt: Likewise.
* config/sparc/nbsdelf.mt: Likewise.
* config/i386/nbsd.mh: Add solib.o, solib-svr4.o to NATDEPFILES.
* config/i386/nbsdelf.mh: Likewise.
* config/m68k/nbsd.mh: Likewise.
* config/ns32k/nbsd.mh: Likewise.
* config/powerpc/nbsd.mh: Likewise.
* config/sparc/nbsd.mh: Likewise.
