I can do that in the rebaseall script (I have a matching patch locally),
but it looks like a race we can't win in the long run.  240 Megs less
space is a lot given the number of DLLs in the distro.

To make matters worse, I just checked my local 32 bit W10 and it turns
out that various Windows DLLs loaded by default (even in a simple tcsh)
are at even lower addresses, e.g.=20
