creating a C++ shared library with libtool using Solaris CC fails

[Bruno Haible]

Hi,

On Solaris 7, with "cc" and "CC" but not gcc or g++ in the PATH, libtool
simply omits the mail link command that is needed to create a shared
library:

  /bin/bash ./libtool --mode=link CC -O  -g    -o libasprintf.la -rpath 
/usr/local/lib  lib-asprintf.lo autosprintf.lo  

results in the following commands to be run:

  (cd .libs && rm -f libasprintf.so.0 && ln -s libasprintf.so.0.0.0 
libasprintf.so.0)
  (cd .libs && rm -f libasprintf.so && ln -s libasprintf.so.0.0.0 
libasprintf.so)
  ar cru .libs/libasprintf.a  lib-asprintf.o autosprintf.o
  ranlib .libs/libasprintf.a
  creating libasprintf.la
  (cd .libs && rm -f libasprintf.la && ln -s ../libasprintf.la libasprintf.la)

but no .libs/libasprintf.so.0.0.0 is created.

How to reproduce:

  - Fetch gettext-0.12.tar.gz or gettext-0.12.1.tar.gz from
    ftp://ftp.gnu.org/pub/gnu/gettext
  - Unpack it
  - cd gettext-runtime/libasprintf
  - ./configure
  - make

This is a regression in libtool-1.5 versus libtool-1.4.3.
