[Coin-symphony] enable-gnu-packages

[Ted Ralphs]

Hi Martin,

Sorry about the problems with stopping SYMPHONY. What is supposed to 
happen if you answer "y" to the prompt is that SYMPHONY is supposed to 
stop what it's doing (gracefully) and then report the current (partial) 
results before exiting. The intent was to allow a user to kill a solve 
call without losing the best solution that had been generated so far. Is 
this what is happening? When you say that SYMPHONY continues on, how 
long does it continue on for? It may take a few seconds for it to finish 
what it's doing and collect the information it needs to report. Can you 
send the output of a call where you tried to call it and it didn't stop?

In any case, the signal catching does not seem to work well on some 
systems, so we will turn it off by default in a future release, but for 
now, there is no (easy) way to disable it (unfortunately). If you wait a 
few days, we will try to implement an option to turn it off and make a 
new patch release.

As for your problem with --enable-gnu-packages, can you send the 
config.log file from your build, so we can see what's happening?

Cheers,

Ted
