Any idea what's wrong and how we can finally fix the libgcc shared

The makefile is created via t-amigaos.
It should not have been ALL_CPPFLAGS, I wil try to check where to set the
difines this evening. Will work on it as soon as I get home from work.
Attached patch to /gcc/gcc/config/rs6000/t-amigaos
Now creates a 359 KB version of libgcc_s.so
Great. Now it seems to work as all the functions our old native
libgcc.so has is now also in the newly generated libgcc_s.so. Very good
job Henning. Now we just need to get our binutils changes updated to the
latest 2.18 version. I know you once tried to port our current 2.14
changes to 2.17, but it didn't work out as expected. Have you perhaps
retried recently to get our binutils changes ported to 2.18? AFAIK
Hans-Jörg could really do with a newer binutils port so that we get a
better unix-like shared library integration in OS4.
If you delete libgcc_s.so and delete mklibgcc and run make again, then you
do not need to rebuild everything.
Well, it only takes about 10 minutes on my AMD64 multicore linux machine
to build the whole native GCC suite. So that's really no issue here.
So again. Great job Henning. And I just comitted your changes to our
repository and will hopefully build a new full native compiler suite
with the update libgcc.so and libstdc++.so
So next would really be to get binutils updated as soon as possible.
After that I can then try again to port our GCC changes over to the
latest 4.3.x version of GCC - but my first try failed due to the large
changes the GCC crew did to the 4.3.x versions including the requiring
of the mpfr library now which we would definitly require to port if we
want to build native versions of GCC in future again.
cheers,
jens
