annotate dmd/cond.h @ 1404:11b122f92136
Now that templates instantiations are no longer emitted for all modules that
even blink at them they seem to break due to being linkonce (if compiled with
any optimization level > 0), so let's give them weak linkage instead.
The difference is that unreferenced linkonce symbols can be deleted, while
weak symbols need to be preserved.
