This is not needed for as far as I understand (there is no libgcov.a). 3.2.2 
binaries are built, but not yet uploaded and are

No real testing done (except the bootstrapping of course). Also profiling is 
not tested.

Maybe I'll take a look when build some gcc-3.3 snapshot sometimes. I don't 
know when I'll do that, as I'm using DJGPP very little in last time (I'm 
mostly using Linux now)
