Bootstrap fails during libjava on some targets
This is apparently due to the extremely long command line of 73,379 characters
given to the linker.
Though it seems Automake should be able to handle this itself, I would think
this could be circumvented by splitting the link into a several convenience
libraries and then linking those together.

Actually I thought we are already doing this ...
Well, to be honest libjava on darwin < 7.0 does not make much sense. You can
only use a subset of the library for very limited functionality. The big part
missing is the shared library support. For example all the SWING/AWT part you
can't use since the libgcc is statically linked in for several libraries.
Andreas, can we document the "minimum Darwin 7.x" requirement somewhere -
perhaps install.texi? Perhaps we should also set up configure to only build
libjava by default on Darwin >= 7.0.
oh, now I seem to remember why shared libraries are not supported under darwin <
7.0. Afair it was due to the missing MD_FALLBACK_FRAME_STATE_FOR macro at the
time when I introduced the changes for shared libraries on darwin.
Now this macro is in and it should also support darwin < 7.0.
You may try to modify ltcf-c.sh, ltcf-cxx.sh, ltcf-gcj.sh and ltconfig in the
toplevel gcc dir. See where it says:
case $host_os in
To say yes for darwin6.x too. It may help. I don't know since I no longer have a
6.x machine around. Just an idea.
a) Changing the lt* scripts had no effect.
b) This problem also happens under cygwin.
The original thread has a patch:
The patch fixes the problem on cygwin. On its face it certainly appears that it
would also fix the problem under the older OS X versions. I recently upgraded
my iMac to OS X 10.3, so I can't test it there. Perhaps Lars could help as he
also reported the problem.
As the initiator of the PR, I would support its closing upon installation of the

I'll test that by the time the next weekly snapshot of head is out.
I successfully bootstrapped gcc-4.0-20041003 on Mac OS X 10.2.8 (powerpc-apple-darwin6.8). This
bugg seems to be fixed here too.
This bootstrap bug unfortunately became re-introduced with this Richard
Henderson patch which moved the command line linking the thousands of sources
directly from libgcj.la to a convenience library libgcj0_convenience_la. This
commandline happens to be 94,720 characters long which exceeds reasonable
This should be pretty straightforeward to fix by moving Tom Tromey's previous
clever hack to the new convenience library. I'll try that and report back the

This was filed under PR 20155.
The orginal problem was fixed but showed up again via soemthing. Next time open a new bug instead
of reopening this one.
