Subject: Simplify USE_ALIGNED_ALLOC
X-Git-Tag: emacs-26.0.90~2740
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=0815944ac4a190d1402079453b99d00fcc26dc25;p=emacs.git

Simplify USE_ALIGNED_ALLOC

* src/alloc.c (USE_ALIGNED_ALLOC): Simplify, now that we’ve merged
in the emacs-25 changes.  Omit no-longer-needed decl for aligned_alloc.
