So we properly simulate sst/sld instructions.
autoconf.

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.
