Hello Steffen,

Many flavors of linux still have gcc3 available. It is often called
"legacy gcc" or something like that. I know that CentOS and OpenSUSE
still have it. You can sometimes get it for Ubuntu buy using an older
repository.

I still compile and use gcc3/g77 code for 64-bit linux and this works
just fine, so I would suggest finding an acceptable linux that still
supports gcc3 instead of doing something more complicated.
