* ltcf-cxx.sh: On Darwin, make archive multi-module, and don't
use -all_load flag.
Index: gcc/ChangeLog
2004-08-02 Geoffrey Keating <geoffk@apple.com>
* dwarf2out.c (output_call_frame_info): Don't change data format
due to TARGET_USES_WEAK_UNWIND_INFO. Always refer to the local
label. Use 'true' not '1'.
* doc/install.texi (powerpc-*-darwin*): Mention cctools version
required.
