	* ltcf-cxx.sh: On Darwin, make archive multi-module, and don't
	use -all_load flag.

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.

@uref{http://developer.apple.com/tools/compilers.html} (free
registration required).
The default stack limit of 512K is too small, which may cause compiles
to fail with 'Bus error'. Set the stack larger, for instance
by doing @samp{limit stack 800}. It's a good idea to use the GNU
preprocessor instead of Apple's @file{cpp-precomp} during the first stage of
bootstrapping; this is automatic when doing @samp{make bootstrap}, but
to do it from the toplevel objdir you will need to say @samp{make
CC='cc -no-cpp-precomp' bootstrap}.
This version of GCC requires at least cctools-528.
The version of GCC shipped by Apple typically includes a number of
extensions not available in a standard GCC release. These extensions
are generally specific to Mac programming.
are generally for backwards compatibility and best avoided.
