This is _very_ old code. Back in the day, before we started to strongly encourage people to use our compiler, we had to deal with tons of different versions of the toolchain.

As the comment to the code indicates, 16bit relocations worked for some and failed for others. Therefore we went for the safe route and manually created a 32bit relocation.

We could probably clean up this part of the code now, but since so few people are ever concerned with it (because it does exactly what it's supposed to), there was no pressing need yet.

Regards,

Patrick
