So you just want to say that there is no right way to make it working 
except of using attribute_used or change all static declarations?
OK. I'll ask you in another way. Can you do something to make it 
possible to compile with ICC? I want to make some performance tests and 
decide if Intel's compiler is so stupid.
I've seen significant performance increase when using ICC compared to 
gcc-4.2.2 in some programs.

P.S.  Can't you be more polite with mail list users? I simply asked you 
if it is possible to do something it this situation.

Thank you.
