I'm surprised this didn't help, actually.  Given a string, Buildbot
prefixes it with 'CMD.EXE /c', then puts the whole thing in a
temporary batch file and executes it.  So I'd expect a batch file
containing

CMD.EXE /c xt-size.exe libWhatever.a --totals > memstats.txt

which is exactly what Vasily suggested.  I don't understand why that
wouldn't work..
