I'm very unhappy about having two separate handles to the file - one
for reading the data through file(d)_open and another through
fopen. Given that starting capture is done through a CLI command
(presumably), the exact time of this is not that useful, IMHO. This is 
the only thing we gain.

I've fixed ascend.c and ascend-scanner.l to get this to work with gzip 
files now. The .txt file you sent me seems to have broken times as you 
mentioned. Gilbert sent me a .gz-ed ascend trace which seems to load
fine. Incidentally, the progress bar doesn't move with Ascend captures 
- though I don't believe this has changed.

I'm going to test it on my Sun box, then check it in unless you want
me to change anything?
