VC++ generated image seems stable and fast

I have been able with the:
===
#pragma optimize("g", off)
static INLINE signed long int ObjectPointer_asSmallInt(ObjectPointer oop)
{
return ((signed long int) oop) >> 1;
}
#pragma optimize("g", on)
===
'patch' to compile a new VM with:
vcvars32.bat (VC++ Toolkit 2003 directory)
and:
cl -Ox -DNDEBUG=1 vm.c file.c boot.c
in a directory with all files from platform directory + vm.c and vm.h from
alpha directory,
to build a working VC generated VM.
I have generated a new VM from this VM, and generated new Bootstrap image
from it too.
If VC unoptimized VM was VERY VERY MUCH slower than optimized GCC (from
MINGW),
optimized VC VM seems faster than MINGW optimized one.
