#38678: xdelta1 @ 1.1.4 Fix aclocal warning caused by underquoted definition in
xdelta.m4
---------------------------------+--------------------------------
 Reporter:  Torsten.Maehne@…     |      Owner:  macports-tickets@…
     Type:  defect               |     Status:  new
 Priority:  Normal               |  Milestone:
Component:  ports                |    Version:  2.1.3
 Keywords:  haspatch maintainer  |       Port:  xdelta1
---------------------------------+--------------------------------
 The xdelta.m4 file installed by the xdelta1 port to
 {{{/opt/local/share/aclocal/}}} causes an annoying warning each time
 {{{aclocal}}} is run:
 {{{
 /opt/local/share/aclocal/xdelta.m4:7: warning: underquoted definition of
 AM_PATH_XDELTA
 /opt/local/share/aclocal/xdelta.m4:7:   run info Automake 'Extending
 aclocal'
 /opt/local/share/aclocal/xdelta.m4:7:   or see
 http://www.gnu.org/software/automake/manual/automake.html#Extending-
 aclocal
 }}}

 The fix is described in https://bugs.archlinux.org/task/20895 but won't
 probably applied upstream, as xdelta 1.1.4 is an old stable maintenance
 release superseded by Xdelta-3.0. I attach a patch updating the Portfile
 and including the patch.

 Could some maintainer with commit rights to the repository please apply
 the patch?
