* Makefile.in: Get rid of srcroot. Set all INSTALL macros via

autoconf.
	* gencode.c (write_opcodes):  Pad operands field to account for
	MSVC braindamage.
	* simops.c:  Include errno.h.  Exclude SYS_chown, since MSVC
	doesn't support it.  (Why is this here in the first place?!?)
	* v850_sim.h:  Get rid of 64 bit defs.  Also, get rid of #elif's.
	Change number of operands in struct simops from 9 to 6.  Define
	SIGTRAP and SIGQUIT for MSVC.
