Unfortunately, the analysis of the routine __fixunssfsi, shows that some
absolute calls remains (a couple of jsr !!!!). In the previous version
of gcc (4.2.3)
Are you linking with static or shared libgcc? That function is in
libgcc and if you link to a libgcc that wasn't built PIC then it follows
that it will have absolute addressing.
What target is this? If you want you can probably change the multilib options to specify that libgcc should be built -fPIC when static. It looks like OpenBSD does this already, see config/m68k/t-*.
