/* Cygwin allows applications to provide their own malloc.  As of
cygwin-1.7.24, applications that provide their own malloc are also
allowed to provide their own posix_memalign (but not memalign).  Calls
to memalign are handled by Cygwin's memalign, which always returns
ENOSYS if the application has defined its own malloc.  So we have to
rename memalign in order to make sure that posix_memalign calls
Emacs's memalign rather than Cygwin's.  */

How does Cygwin memalign come into play, when Emacs provides its own?

As I said in the comment, Cygwin does not let applications define their
own memalign.  During linking, calls to memalign become calls to
Cygwin's memalign.

Hold on...I think I'm missing something obvious.  I have to recheck this.
