Symbols for address space bounds

[Boehm, Hans]

I finally integrated this into the most recent collector distribution.  It seems to work fine, thanks.

However, I don't think we ever resolved the issue about the stack base, and particularly a replacement for __libc_ia64_register_backing_store_base and __libc_stack_end.  The problem is that I need to determine this from a library without control over the main program.  Any ideas?  (You suggested fixing pthread_getattr_np for the main stack.  That would be nice, but that it inappropriate in the single-threaded case.)

Thanks.

Hans
