Yes it is possible.  I do it daily.

Specifying `--enable-threads' is the same as `--enable-threads=no'.
I find this confusing, but I don't have the time to take it up with
the egcs developers.

Use --enable-threads=posix instead.

You want to configure egcs with the right --enable-threads value in
order to get threadsafe exception handling.

This looks right.

There's a known bug in this code.  Thread.sleep() (at least on Linux,
with POSIX threads) doesn't actually sleep.

I haven't had a chance to debug this :-(
