Yes, that's correct.  The problem with the garbage collector is
fixed in the latest development snapshot of Mercury.
The gcc code generation bug is fixed in the version
of egcs and bintools from Mumit Kahn's ftp site.

So if John Velman just tries the latest development snapshot of Mercury,
which is available from < >,
it should work, I think.  The "official" recommendation is still to stick
with b18, but that is just because we've only done very minimal testing
with b19.1.

The problem with the whole machine hanging is apparently a bug in Windows 95.
A patch is available, I believe -- see the cygwin32 FAQ list.
