AFAIK the 030 kernel is compiled with -m68030. You see this if you take a
look into the Makefile or if you recompile the kernel on the gcc
commandline.

That's not true. The spec file translate (for the cpp) the machine
specific compiler options into the required default defines for this
machine option. And as m68020-60 implies m68881 __M68881__ is defined.

This implies that the GCC optimizer unit work correctly. If you use the
C++ part a little bit you will encounter lot of optimization bugs in the
C++ itself. Lot of C++ code you cannot compile with -O3 or -O2 correctly.
