Hi !

Sorry for the late mail, but I was busy earning money ;-)

I'm getting mysterious warnings about
"Unused source" from "v2/build/targets.jam:969"

while trying to declare targets which have to be compiled with 
<optimization>off.

This can be reproduced using the "railsys"-test case in v2/test/railsys
The output of current CVS state is attached in railsys.out.1.txt
After applying attached railsys.diff (removing the extra rule for 
compiling without optimisation) railsys.out.2.txt show the expected 
output.

This is broken since the last major changes to V2. 
Unfortunately, I had no time to report this earlier and simply had to 
comment out the output ;-((

And I had trouble using my Yahoogroups-Account.

Any Ideas ?

Yours,

Jürgen
