  Mixed results so far.  Patching a binutils checkout and building it got me
this:

..which is entirely good :-D  Then I tried a winsup checkout; it failed to
configure in newlib:

Usually this means the macro was only invoked conditionally.

Usually this means the macro was only invoked conditionally.


  Note the huge jump:

configure:3817: result: no
configure:21892: checking for .preinit_array/.init_array/.fini_array support

interestingly enough, the only line after 3817 that has a conditional and that
precedes any more printout is at #3939, where it says ...

if test "${use_libtool}" = "yes"; then

and the clause that would set am_fastdepCXX is at 7496 to 7505, which is
probably still inside that conditional.

if
  test "x$enable_dependency_tracking" != xno \
  && test "$am_cv_CXX_dependencies_compiler_type" = gcc3; then
  am__fastdepCXX_TRUE=
  am__fastdepCXX_FALSE='#'
else
  am__fastdepCXX_TRUE='#'
  am__fastdepCXX_FALSE=
fi



  This happened by following your procedure in
http://sourceware.org/ml/gdb/2007-03/msg00284.html.  I did the following
steps:

- take existing checkout of 'winsup' module, 
- clean it out with
 cvs up -CAdP config contrib etc include libiberty newlib winsup
 cvs up -lCA .
- kill the four libtool config files
  rm ltc*
- untar the libtool tarball
  tar xzvf libtool.tar.gz
- regenerated newlib as in your email
  cd newlib ; aclocal; automake --cygnus; autoconf

Then configured in an out-of-tree object dir with no options other than
--prefix and -v.

  Any idea what to try next?  It looks a bit like the problem with
AM_CONDITIONAL discussed at

http://sourceware.org/ml/automake/2005-01/msg00037.html



    cheers,
      DaveK
