 isn't in, see #14406 for details on this where JP mentions it.  So that's
 two issues.

 ATLAS on Cygwin by default.
 Yes, I realize all this; I was just saying that at least there was a
 useful error message in some patch/spkg somewhere on that ticket.

 Yes, though those aren't necessary to close this ticket.

 64 and 8 64 I'd say), preferably not virtual machines, but let's not dream
 too much.
 Umm, no!  Especially since I can't get testing to even work on XP 32 -
 presumably because every time I rebase, I get a different problem related
 to having not enough space.  I wonder if deleting all the dlls in
 devel/sage/sage/ would work, since the ones in devel/sage/build/ are the
 ones that are actually (currently) used?
