if you compile the dfl Library to 64 bit,you will find error:

core.sys.windows.windows.WaitForMultipleObjects(uint
nCount,void** lpHandles,....) is not callable using argument
types(ulong,void**,...)

the 'WaitForMultipleObjects' Function is in
dmd2/src/druntime/src/core/sys/windows/windows.d

the argument of first is dfl's value ,it come from a 'length'
,it's type is size_t,now it is 'ulong' on 64 bit.

So druntime must keep the same as  phobos for size_t.
