Yes you are!

There are two main problems.
1. Sun
  Sun wants to sell you the cross-development-package and so the cc suplied
  with your sun3 won't generate plain 680[01]0 code. The "-sun3" (for 4.0.3)
  or the "-target sun2" (for 4.1) wont work without the cross-development-
  extentions. I suppose "as" does the same (not testet - I fixed gas to work)
2. GNU
  The gas doesn't work correct on sun3!!!!! There are problems (never fixed by FSF)
  that make it incompartible to the as. These are not only syntax-problem
  there is a GREAT BUG in gas, that brings semantik-problems with the bss
  segment. Under 4.0.3 (we are still running 4.0.3, because sun isn't able
  to ship the sources) it was poosible to install gas (with a lot of work)
  but under 4.1 I dont know if it is still possible. (on Sparc these
  semantik-problems make it impossible to use gas!)

If you got a correct objectfile, everythings done. "ld", "ar", "ranlib, etc. works!
