+commit 3c9e50cb0bf42f42f0be460e89045257c7efc480
+Author: Alan Coopersmith <alan.coopersmith@oracle.com>
+Date:   Mon Jan 24 22:55:18 2011 -0800
+
+    Remove dependency on libXaw
+    
+    The only thing from libXaw that isn't in #ifdef NOTDEF is a reference
+    to the ZERO #define, which is trivially replaced - no point requiring
+    an entire library for a single constant #define.

-#
-# Automake 1.8 used `mkdir -m 0755 -p --' to ensure that directories
-# created by `make install' are always world readable, even if the
-# installer happens to have an overly restrictive umask (e.g. 077).
-# This was a mistake.  There are at least two reasons why we must not
-# use `-m 0755':
-#   - it causes special bits like SGID to be ignored,
-#   - it may be too restrictive (some setups expect 775 directories).
-#
-# Do not use -m 0755 and let people choose whatever they expect by
-# setting umask.
-#
-# We cannot accept any implementation of `mkdir' that recognizes `-p'.
-# Some implementations (such as Solaris 8's) are not thread-safe: if a
-# parallel make tries to run `mkdir -p a/b' and `mkdir -p a/c'
-# concurrently, both version can detect that a/ is missing, but only
-# one can create it and the other will error out.  Consequently we
-# restrict ourselves to GNU make (using the --version option ensures
-# this.)
