Greetings,

In core.varar. 
(https://github.com/D-Programming-Language/druntime/blob/master
src/core/vararg.d), 
why is the X86 implementation singled out and written in D rather 
than leveraging the standard c library implementation like the 
others?

No idea.  It seems like a pointless duplication of code.  Maybe 
just to have some documented functions within the module?

In that case, a better question is "Why use the standard C 
implementation if we have working D code?".

Less to maintain. Also, there's less risk of inconsistency with what C is
doing. And it's low level stuff anyway where it doesn't really buy us much
to implement it ourselves rather than just hooking into the existing C API.
