Isn't that just the normal message when running `sage -sh`?

Indeed! I thought it was some cygwin special but it is in
$SAGE_ROOT/src/bin/sage at lines 735-742.

I never even read it that closely. Why *does* it say that? I install
packages and run make from within the sage subshell all the time.
Especially when it comes to optional packages (which should maybe be the
only kind actually supported by sage -i) there should be little danger.
What about removing all this then?

The only danger is if you somehow break the python in Sage. I've actually
been thinking about that lately and I don't think it should ever be used by
sage_bootstrap. I think it should always try to find the system Python
instead.

It is unlikely that you break Python with a "pip install" or
"sage -i". If you do something else in "sage -sh" I assume
you are advanced enough user to figure things out.

Dear all (I guess mostly Erik),

When a sage shell is launched on windows (ie the sage -sh environment in
cygwin) the following message is displayed

"""
Starting subshell with Sage environment variables set.  Don't forget
to exit when you are done.  Beware:
   * Do not do anything with other copies of Sage on your system.
   * Do not use this for installing Sage packages using "sage -i" or for
     running "make" at Sage's root directory.  These should be done
     outside the Sage shell.
"""

Many people at Sage days 96 cut the second item as
"Do not use this for installing Sage packages" and they did not
even tried to "pip install" the Python package I asked them to
install (I gave them the full command to be run).

Would that be possible to simply disable "sage -i"?

PS: Erik, once more, thank you for this cygwin version that is
wonderful to get more Sage users!!
