looking through it, I can try the perl bug again but the other
bugs are either out of reach at this stage or not linux.
If I find time I will try to look at the bootstrapping problem.

possibly not many people with m68k targets do bootstrapping
very often nowadays - afaics only debian-m68k.
Eg the warning you have just recetnly fixed in CVS would make
every bootstrap attempt fail on all m68k plattforms, not just
linux.
