Sounds like you're using an outdated OPTLINK. The /LA flag was added 
relatively recently and the newer DMD buildscripts use it.

Try updating your copy of DMC, maybe a newer one will have the 
up-to-date OPTLINK. Or just replace your DMC's OPTLINK with the one that 
comes with DMD 2.064.2:

Not sure what's up with that one, but I don't have any familiarity with 
mtype. Maybe it's just fallout from the earlier error?
