Eddie, many thanks for including the binary of your version of double.
I transfered that to my TS7200 and it works! Great.

I've downloaded from the

 http://www.embeddedarm.com/linux/ARM.htm

page, and checked it's the same version as you quoted. So tonight when I
get home I'll upgrade on my development box.


Many thanks for the help.

Jim
