Just a plea to anyone who reads this.
Please don't send in reports that configures are really slow unless you
can provide some insight.
With the last several snapshots and with B20 itself we've received a lot
of reports from people who excitedly noticed things that were mentioned
in Geoff's announcement mail.
Just in case it isn't clear, here are some things I, personally,
do not want to hear:
1) Configures do not seem to run very quickly.
2) Configures are really so slow that I can't use them.
3) Configures were slow so I dropped back to B18.
4) Configures are very much like a tortoise.
5) I wrote a shell script and put a lot of commands in it. I use
many pipes and backticks in it to store values in variables. Then
I use sed to massage stuff like Makefiles.
It's really slow.
6) I know you mentioned something about configures being slow but
I wanted to let you know that they are slow here too. I'm using
Windows on a PC. Hope this helps!
7) I think I figured out why configure is so slow: It's taking a long
time for the commands to execute.
8) I tried putting a .bat extension on my configure script. It wasn't slow
but it didn't seem to work quite right.
9) My cofnigure seems to be hung. I've let it run for two horus and it
isnt done yet.
10) How do I strip the \r's from a file? I don't want them. I think this
should be handled automatically so I don't have to worry about it.
I can't see why they don't do this.
Hope this helps.
