some outstanding (minor) issues for branch-2-0

[Ralf Wildenhues]

Could (one of) you please take a look this win32 issue
http://lists.gnu.org/archive/html/libtool/2005-03/msg00158.html
to decide whether that is the right way to fix this problem?

This line in m4/libtool.m4 might be too long (>2048 chars) for some
shells (I noted this because AIX vi did not like the generated configure
script):

| # Quote evaled strings.
| for var in lt_decl_all_varnames([[ ]], lt_decl_quote_varnames); do

We may be able to do something like backslash newline after each name
while constructing the list?

`configure --help' lists some stuff twice: --disable-libtool-lock and 
--enable-ltdl-install/--disable-ltdl-install.  Proposed patch below.

We install argz.m4 into user's AC_CONFIG_MACRO_DIRs.  Is this actually
wanted?

`make install' of branch-2-0 currently fails for me:
m4 files are in share/aclocal/m4/, config.guess in
share/libtool/config/ but tried to be chmod'ed in share/libtool/.

And of course, there are a few pending forward/backward/sideward ports..

Cheers,
Ralf
