Thanks for your help!
  This isn't a big deal, but I'm just trying to understand more fully how 
all this works: I do notice that crtdll.dll is still being linked
in. (I tagged on an objdump -p at the end of this.) I thought from what I
read earlier that msvcrt.dll was basically a drop-in replacement for
crtdll.dll, but apparently that's not totally true? That there are still a
few functions in crtdll that msvcrt doesn't have?
