Result1: 860-sysv3
Result2: 860-mach3
Result0 passed and works (modifications: touch c-parse.y).
Results 1 & 2 failed at installing (see modifications).

That fini_section wasn't defined and FINI_SECTION_FUNCTION macro

Both of the results passed the compilation (with warnings).
And both them failed to compile hello_world program on host computer.
Stupid question:
Is the cross-compiled gcc supposed to work only on that processor?
The other alternative is that it would work on host processor, but
would compile binaries for the other processor.
