the way that callback.o, gentmap, targ-vals.h, targ-map.c,

necessary. This replaces the merging of libcommon.a into

is zero extended for sst/sld instructions.

So we properly simulate sst/sld instructions.
autoconf.
* gencode.c (write_opcodes): Pad operands field to account for
MSVC braindamage.
* simops.c: Include errno.h. Exclude SYS_chown, since MSVC

Change number of operands in struct simops from 9 to 6. Define
SIGTRAP and SIGQUIT for MSVC.

clear the high bits.
* interp.c (Convert): Fix fmt_single to fmt_long to not truncate.
Fix float to int conversions to produce signed values.

This is needed because for certain builds the size field being given
to malloc() is actually 64bits long, and without a cast or malloc
prototype the resulting value used by malloc() depended on the host
endianness, and how long long paramaters are passed into functions.
* interp.c (sim_monitor): Improved monitor printf
simulation. Tidied up simulator warnings, and added "--log" option
for directing warning message output.
