Thanks, but could you please make the commentary more clear? I'm afraid it doesn't make sense to me: if posix_memalign calls memalign, then why does the latter have to be renamed, if all you want is for it to be called? Why won't it be called unless renamed?
How's this: /* 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. */ Ken
