GDC D.2.063 merge

[Iain Buclaw]

Before anyone who's testing / using the development sources of 
gdc raises any issues, yes there are some problems with some of 
the new features in D 2.063. The most serious bugs have been 
squashed and will be pushed out today.

(PS: a little bird told me that gdc will be added to the auto 
tester some time this week)

Iain
