This has caused problems with the GTK build of Emacs on Cygwin. The problem became worse with the latest Glib update. Anyone who wants the gory details can find them starting here:

Cygwin was just patched today to allow applications to supply their own posix_memalign (but not their own memalign), which solves the Glib problem. But posix_memalign in gmalloc.c calls memalign, so I need to make sure that it calls Emacs's memalign. The attached patch does this. Is this a reasonable way to handle the problem? (I plan to also add an explanatory comment.)

Thanks.
