Actually, it's not commented out; it's in a version(0) {} block (at 
least in my copy of Phobos)
.
A "version(0)" doesn't have any effect though. From the spec:
---
The VersionCondition is satisfied if the Integer  is greater than or 
equal to the current version level, or if Identifier matches a version 
identifier.
---
Since 0 seems to be the minimum level (DMD won't let me specify a 
negative "version level") the code will always be executed (similar to 
"version(all)").
