From f2876d1ee3b878a07b12ddcb464633a44f7c29e7 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Remove the logic that determines at compile time whether or
 not HAVE_ALIAS should be defined.  It was flawed on some platforms (e.g.,
 Darwin & mingw). Instead, rely on the build system to define it on the
 compiler command line.

This also reverts ajax's hand-edit to indirect_size.c.  I'll fix that on the
X.org side of things later today.
