RE: Problems with cvs-libtool and Solaris CC

I've looked at this in depth, and the problem does not appear for me.
The main difference I see in my "libtool" script generated using Solaris CC
is that AR="ar" for every tag.  As it should be, old_archive_cmds uses 'CC -xar'
in the CXX tag, but it doesn't change AR.  I don't think this problem
is still in CVS libtool, but mine isn't 100% current.

Yikes!  I assume that this problem results from using C++-based
convenience libraries?

The purpose of 'CC -xar' is to support a template repository.  Given
this, it is likely that the archive file doesn't contain everything
since the template instantiations will be stored in the template
repository subdirectory.  It may be impossible to accomplish the
equivalent of 'ar -x'.
