Can you please tell what you mean by that? Are you alluding to
lisp_align_malloc and its subroutines, or to something else?

I hope Emacs is not on its way to become a glibc-only project. Quite
a few supported platforms don't use glibc: Cygwin, *BSD (AFAIK),
Windows.
Are platforms that use gmalloc.c, with or without ralloc.c, OK in this
regard? If not, what feature(s) are missing that are present in
glibc?
