Can one of you explain how this avoids the problem mentioned in the removed
comment, of malloc_get_state/malloc_set_state incompatibility on powerpc32?
I think the main use case for this is an Emacs that was built (and dumped)
using an older libc, and then run with a newer libc. Is it verified that
an existing powerpc32 Emacs binary is not broken by running against a libc
with this change?
Thanks,
Roland
