[Swarm-Support] Problems with GCC 4

[Steve Railsback]

Hi --

I know some other people have been having issues with GCC lately but I 
couldn't find an archived message that helped us.

Our sys admin just updated the SUSE machines to SUSE 10.0, which 
includes GCC 4.0.2. This version of GCC is causing us problems. It 
created a lot of scary warnings in compiling Swarm, but it did compile.

Then we had to make some changes in our Swarm model code to get it to 
compile. E.g., we had to move some import/include statements around 
(from the .m to the .h files).

We are still getting bizarre warnings; I include some examples below.

And we're finding that parameters we load using ObjectLoader are not all 
being read correctly- some are given absurd values or NaN.

Can anyone explain what's going on and/or suggest a solution?
(We tried compiling GCC 3.3.1 to revert to it and that failed for 
reasons we couldn't figure out.)

Thanks,

Steve Railsback & Steve Jackson
