That segment of druntime.

You can get dmd to do it for you by using the `-i -i=core.sys` 
flags (or maybe just the -i=core.sys thing im not sure i haven't 
actually tried).

Or just stop using -brokenD and find joy lol

In C, that I_ISDIR is a macro in the header file so there's 
nothing to link, it all gets inlined by the preprocessor.
