Maybe use this instead of -I?

`-isystem DIR'
     Add a directory to the beginning of the second include path,
     marking it as a system directory, so that it gets the same special
     treatment as is applied to the standard system directories.

I haven't tried it, since I don't use gcc3.
I just saw it in: info gcc inv pre .
