bug with automake + libtool

[Eric Magnien]

Dear GNU developers,

I want to report you what seems to be a bug in automake-1.4g (problem not seen
with 1.4f):

when using libtool shared library into a *sub-directory* of a package, the
libtool-related `clean' targets are missing from the associated Makefile.in
(this is not true with top_srcdir Makefile.in)

I could reproduce this with the simple Makefile.am/configure.in files below:

==============================
top_srcdir/Makefile.am
==============================

SUBDIR = subdir
lib_LTLIBRARIES = libfoo.la
libfoo_la_SOURCES = foo.c

==============================
top_srcdir/subdir/Makefile.am
==============================

lib_LTLIBRARIES = libfoo.la
libfoo_la_SOURCES = foo.c

==============================
top_srcdir/configure.in
==============================

AC_INIT
AM_INIT_AUTOMAKE(mypackage,0.1)

AC_PROG_CC
AM_PROG_LIBTOOL

AC_CONFIG_FILES([
  subdir/Makefile
  Makefile
])
AC_OUTPUT

------------------------------
