Ack!  Fixed now.  Thanks :-)

Yup.  I mostly did it to be safe.

I'd considered moving it somewhere else entirely (gcc, perhaps) and just 
naming the module std.c.stdarg internally, but I have no idea if that 
would work with the way intrinsics are handled in GDC.  If you're 
inclined to try this and it works, however, please let me know.  If this 
becomes a long-term fix I may also look into having GDC install them as 
you suggest.  I'll admit I'm still secretly hoping to not have to 
maintain 'std' to support intrinsics forever.
