Error Message "ModuleInfo class is incorrect"

[Mike]

I'm trying to port the D Runtime, incrementally, to the ARM 
Cortex-M (thumb2) platform.  But after bringing object.d in, I'm 
getting this error message:

"object.d ModuleInfo class is incorrect"

Looking through LDC's source code, I found the following in 
toobj.cpp

// check for patch
else
{
#if DMDV2
	unsigned sizeof_ModuleInfo = 16 * PTRSIZE;
#else
	unsigned sizeof_ModuleInfo = 14 * PTRSIZE;
#endif
	if (sizeof_ModuleInfo != moduleinfo->structsize)
	{
	error("object.d ModuleInfo class is incorrect");
	fatal();
	}
}

I'm not sure if PTRSIZE is not properly defined for my platform, 
or if I need to make changes to ModuleInfo, or some other problem.

Please advise.

Thanks,
Mike
