They don't blindly overwrite each other. If USE gif is set libungif installs 
gif_lib.h; otherwise giflib installs it. (Or the other way around, I'm not 
sure anymoer).

If you change the value of USE gif between installing giflib and libungif, you 
can get a system with no gif_lib.h, or a system where both packages install 
it, overwriting it. (It's not checksum-identical between the two packages.)

Do read bug 18820. I filed it about this two years ago and nothing changed 
since.
