Right.  As I said, the code in question used to be required.  It is no
longer necessary with the new libtool, so this no longer an issue.

ACE is fairly easy to configure on supported platforms without the
configure script.  Are you porting ACE to another platform?

The code itself in the configure.in file in question states that it is
a hack:

dnl FIXME: Temporary hack to make libtool work with g++.
dnl        Shared library support will only work with GNU g++ and GNU ld
dnl        right now.
dnl save_CC="$CC"
dnl CC="$CXX"
[snip]
dnl Temporary hack until I get integrate libtool's new tag support
dnl into automake.
dnl This hack forces libtool to always use the C++ tag.
dnl LIBTOOL="$LIBTOOL --tag=CXX"

so there is no question that it is a hack.  The full text wasn't
posted earlier.  I'm not sure what the issue is here since this code
will be removed once the configure.in file switches over to autoconf
2.5x and libtool HEAD or 1.4b.

Good luck.  :-)
