Right, as I mentioned earlier in the thread, tasking is not working on 
Solaris 9 (SPARC). The sort of workaround (hack in my opinion) that 
worked up to Solaris 8, does not work, as Sun apparently changed the 
behaviour on how in the memory keep track on threads.

Although I fairly sure it won't work, you could experiment with using 
alternative thread libraries, and hope that the ada code is designed to 
change its behaviour. Check in the configure doc for supported threading 
models by gcc, and hopefully those works with ada rts as well.

In the gnat 5.0 sources there is a new implementation, which I have 
tried to use in 3.3 (not 3.3.2), but it did not work. Fault on my side 
I'm sure.
The upcoming version of gcc is rumored to have a newly synced ada tree 
from the latest? gnat, so we will have to wait and see.

I'm currently on Solaris 8, so I have no problem using tasking in the 
application I'm developing, but migration to Solaris 9 is "on wait" 
until tasking is proven to work.
