_m, 8", and it should have been declared like this: ".bss, _m, 8, 8". 
Really. That's it.

I still don't know exactly how stdw behaves, because the documentation 
really implies that stdw doesn't care about the endian setting, while 
lddw does, but apparently you don't have to care. Using stdw and lddw in 
analogous fashion is OK, at least in little endian mode. So much for
