Does this mean that .exe, .so, and .dll stuff in SAGEROOT/local/ needs
to be rebased as soon as it's created?

I am in particular puzzled by these temporary DLLs in the log:
C:\cygwin\tmp\eclfeH9uJ.dll

Is it Ecl that is creating these temporary DLLs?
Can anyone enlighten us on this?

Basically, it's an ECL bug/feature related to playing fast and loose
with DLLs.
It seems to be a show-stopper on Windows 7 for me.

Is it easy to disable compiling into C by ECL?

You may want to post on sage-devel, or cc: upstream (Juanjo=Juan Jose
Garcia). Upstream has been extremely responsive in general with ECL,
and often does things specifically because we ask about them.

By the way, on that topic, I can't resist posting this -

Lisp program on iPhone, now is your chance!

I would write your concerns to the ECL list. The developer is very
active and quick to respond to problems.

I was suggesting you did it, but if you can create a trac ticket so I can point
them at something, then I'll post it to ecls...@lists.sourceforge.net since I
am a member.

The main developear is Juan Jose Garcia-Ripoll juanjose.g...@googlemail.com

Hi Dave,
there is a ticket for it :)
http://trac.sagemath.org/sage_trac/ticket/11260

Best,
Dima
