+ * tm-vx68.h, tm-es1800.h: Use tm-68k.h rather than tm-sun3.h.
+ * tm-sun3.h: Remove STACK_END_ADDR, no longer used.
+ * tm-sun3os4.h: Update comments.
+ * xm-delta88.h: Remove STACK_END_ADDR.

Wed Sep 2 01:18:31 1992 John Gilmore (gnu@cygnus.com)
* Makefile.in (VERSION): Roll to 4.6.5.
+ * infrun.c: Lint for recent `handle' changes.
+
* ser-termios.c, ser-go32.c: Remove DEFUN crap, clean up.
* serial.h (EXFUN): Remove all uses, convert to PARAMS.
* config/sun4os4.mh: Include ser-termios.o. FIXME, all .mh files
