Please report these issues with gdc in bugzilla so that they can be 
fixed or at least documented.  I'm not sure how carefully david reads 
the non-D.gnu newsgroups and regardless, just a good habit... :)

The StackThreads issue is unclear.. it could be gdc but might well be 
stackthreads itself.

Thanks and good work,
Brad
