--- Comment #10 from Mikael Pettersson <mikpe at it dot uu.se> 2012-05-17 15:02:51 UTC --- See the gcc-patches thread I referred to in #c8, gcc-4.3 also changed low-level ABI details, with the consequence that gcc-4.2 and gcc-4.3 generate incompatible code for m68k-uclinux. If you want 4.3 and newer to behave as 4.2 and older you should use m68k-uclinuxoldabi. Patching m68k/linux.h might work, but it's not a supported configuration.
