Use a rather bare bones d example and trying to compile for x64 in windows by
adding the -m64 switch gave the same results. Seems like it is a conversion
issue due the fact that length depends on the architecture. 

Changing the line in format.d "uint sl;" to "size_t sl;" solves the errors but
then gives

------ Build started: Project: CTest1, Configuration: Release Win64 ------
Building Release\CTest1.exe...
Internal error: ..\ztc\cgobj.c 1479
Building Release\CTest1.exe failed!

Using casts instead of size_t also gives the same error.


The code is

"   else                                // 16 bit segment
    {
#if MARS
        assert(0);  // line 1479
#else
        if (size & ~0xFFFFL)
        {   if (size == 0x10000)        // if exactly 64Kb
                sd[0] |= 2;             // set "B" bit
            else
                synerr(EM_seg_gt_64k,size);     // segment exceeds 64Kb
        }
//printf("attr = %x\n", attr);
#endif
    }"


Which seems to be how the compiler is dealing with object files and the 64-bit
object segments are treated as 16-bit. (A guess as I'm new to D but jives with
what was said about the 64-bit issues DMD had)

In any case the uint seems to be a bug as much of the code surrounding it uses
size_t's.
