Yep. I actually used gcc's -save-temps option with generates the same 
output as -E but conveniently saves it to a file.

See previous email. Somehow the problem is an interaction between <
netdb.h> and <list>. I sent a very simple sample code that triggers the 
problem.

I did not send it because I managed to track down the problem in a very 
simple test case. If you still need it let me know and I will send it 
to you. Of course you can also generate it youtself now as I am sure 
you know how to do. ;)
