+# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN),
 # which have later been changed to m4_define as they aren't part of the
 # exported API, or moved to Autoconf or Automake where they belong.
 #
 # The trouble is, aclocal is a bit thick.  It'll see the old AC_DEFUN
 # in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
 # using a macro with the same name in our local m4/libtool.m4 it'll
 # pull the old libtool.m4 in (it doesn't see our shiny new m4_define
 # and doesn't know about Autoconf macros at all.)
 #
 # So we provide this file, which has a silly filename so it's always
 # included after everything else.  This provides aclocal with the
 # AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
 # because those macros already exist, or will be overwritten later.
-# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6. 
+# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
 #
 # Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
 # Yes, that means every name once taken will need to remain here until
 # we give up compatibility with versions before 1.7, at which point
 # we need to keep only those names which we still refer to.
 
 # This is to help aclocal find these macros, as it can't see m4_define.
