4.5, soon 5 years. There was a lot of work over rebase and it's cooperation
with setup. Can you reproduce this issue today?

I suggest a Linux VM, since you are a teacher.
Strongly suggest.

Which are "these errors"? And how long you are using Cygwin?
If you are using it from before the setup/rebase changes, may be, it's time to
do a fresh install and see, if that would improve the situation?
Or switch to x86-64 cygwin, which have a bit better situation with memory
layout.

Unlikely it's true. More likely, it automatically rebase, but you did not
notice.

Windows and POSIX models require different load techniques.
Cygwin provide POSIX compatibility layer.

Because it's not possible for two reasons.
First, packages are compiled in many different places, and second - there's
just not enough memory to place every possible Cygwin library in 32-bit
address space. Neither it's feasible, as noone need every cygwin package at
once.
> Rebasing should not be the responsibility of the user, but of the developer.

Cygwin users are developers. That's the intended audience, anyway.

It's a simple misunderstanding, overweighted with lack of information.
If you do a search through the mailing list, you can find much better
explanations for the reasons of rebase, than mine.
