Re: [uCsimm] Relocation problem

Only those modules that contain any references to locations outside the
+/-32KB range require compilation with 32-bit (-fPIC). There's nothing
special on the C library, it is just a couple of object modules. The library
contains only inside references, however, and as long as the complete
library is <32KB, all the references are therefore within the +/-32KB range.
Thus, there's no need to compile the library with 32-bit. It doesn't hurt
if you do that, but you'll increase the codesize by ~2-3%.

That is a question that I would defer to Erwin to answer, if the
libraries need to be recompiled as well, I don't believe that they don't
have to be as I belive that only functions are loaded from a library
into memory as opposed to whole library itself.
