* For Mach-O, this is done by constructing a separate segment inside the
* __DATA section for each set. The contents of this segment are an array
* of pointers to the objects in the set.
- *
+ *
* Note that due to limitations of the Mach-O format, there cannot
* be more than 255 sections in a segment, so linker set usage should be
* conserved. Set names may not exceed 16 characters.
