* OS X Synthetic port (partial, incomplete and unlikely to ever work)

Greetings,
I finally got the FSF copyright assignment form and have returned it
to them again. So I figured it was about time to post the aborted OS X
Synthetic port. Just in case someone can make use of it (or parts).
I aborted the port simply because I could not get constructors to run.
OS X comes with its own tools and a special file format, and it
appears that GCC has just adopted this (for obvious reasons).
So the linker and loader is unlike what I know from Linux. In short,
the breakage is due to the linker apparently not loading constructor
sections. Probably because these are intended to be executed as part
of the loading. Unfortunately, I never figured out how to trigger
this. And I got fed up with the challenge. So, abort.
The current state of the patches are pre-V3. Can't be bothered to
upgrade my tree and make the header changes.
All tests build and link in the default configuration. But only tests
that do not make use of constructor sections work (such as the two HAL
tests).
Cheers,
Jesper

+# to the calling conventions all fpu registers are CALL_USED_REGISTERS
+# (gcc/config/i386/i386.h) and will have been saved by the calling

+## Date: 2001-03-16
+## Purpose: Synthetic target startup
+## Description: When running on real hardware vectors.S contains
+## initialization code and usually the low-level interrupt and
+## exception support. On the synthetic target the latter is
+## handled by C code. The main initialization that is needed is
+## to jump into the C startup.

+# According the SVR4/i386 ABI, most registers are undefined. However
+# there is some interesting information on the stack:
+# %esp argc
+# %esp+4 argv[0]
+# ... argv[1 onwards]
+# %esp + (argc*4) NULL
+# ... environ[0]
+# ... ...
+# ... NULL
+#
+# There are some other things that could be done, for example aligning
+# the stack to a 16-byte boundary for SSE, but it is not clear which of
+# those things are actually useful. The glibc source file
+# sysdeps/i386/elf/start.S contains some relevant information.
