* interp.c (Convert): Provide round-to-nearest and round-to-zero
 	support for Sun hosts.
	* Makefile.in (gencode): Ensure the host compiler and libraries
 	used for cross-hosted build.

Allow a DOS hosted version of the simulator to be built. NOTE: The FP
is still not complete, since round-to-nearest and round-to-zero have
not been implemented generically.

* gencode.c, interp.c: Replaced explicit long long references with
 	WORD64HI, WORD64LO, SET64HI and SET64LO macro calls.
	* support.h (SET64LO, SET64HI): Macros added.

This is an intermediate checkin. The work of removing "long long"
usage is not yet finished. These changes are clean, and have been
sitting on my machine for a while (whilst doing other work), and it is
safer for them to be checked in.
