That was a fix for compiling controller units with lots of symbols, refer
to this discussion thread:

Dwarf2 is fine in general, unless the address (I think address in dwarf
debug section, the details are a bit hazy in my memory) of symbols exceed
65535. Dwarf3 offers a larger data type for this scenario.
