-While the GC should work on MacOS X Server, MacOS X and Darwin, I only tested
-it on MacOS X Server.
-I've added a PPC assembly version of GC_push_regs(), thus the setjmp() hack is
-no longer necessary. Incremental collection is supported via mprotect/signal.
-The current solution isn't really optimal because the signal handler must decode
-the faulting PPC machine instruction in order to find the correct heap address.
-Further, it must poke around in the register state which the kernel saved away
-in some obscure register state structure before it calls the signal handler -
-needless to say the layout of this structure is no where documented.
-Threads and dynamic libraries are not yet supported (adding dynamic library
-support via the low-level dyld API shouldn't be that hard).
-The original MacOS X port was brought to you by Andrew Stone.
-June, 1 2000
-Note from Andrew Begel:
-One more fix to enable gc.a to link successfully into a shared library for
-MacOS X. You have to add -fno-common to the CFLAGS in the Makefile. MacOSX
-disallows common symbols in anything that eventually finds its way into a
-shared library. (I don't completely understand why, but -fno-common seems to
-work and doesn't mess up the garbage collector's functionality).
