+Subject: [PATCH] libtoolize: fix infinite recursion in m4
+
+Some projects use this construct in configure.ac:
+
+  m4_define([version], m4_include([version]))
+  pkg_version=version
+
+When the m4_include builtin is undefined (as was done in
+libtoolize and extract-trace scripts), the call to this 'version'
+macro enters an infinite recursion (until ENOMEM).  So rather
+re-define all potentially dangerous macros by empty strings,
+suggested by Eric Blake.
+
+While we are on it, merge the macro-"blacklist" with similar list
+implemented in gettext, except for 'm4_esyscmd'.  It's kept
+defined because we already trace AC_INIT macro for package
+version, while it is often specified by
+m4_esyscmd(git-version-gen).  Similarly to m4_include, m4_esyscmd
+might be opt-in-blacklisted in future.

+
+* gl/build-aux/extract-trace (_G_mini): Redefine trace-breaking
+macros to empty strings rather than undefining those.  Use 'dnl'
+for comments.
+* bootstrap: Likewise, sync with extract-trace.
+* NEWS: Document.
+* NO-THANKS: Mention Hiroyuki Sato.
