<p>It's not a bug, and it's not really a problem. Nevertheless, some
people don't like it, so here are two pseudo-solutions:
</p>
<p>If the only functions from libstdc++.a which you need are language
support functions (those listed in
<a href="../18_support/howto.html">clause 18</a> of the standard,
e.g., <code>new</code> and <code>delete</code>), then try linking
against <code>libsupc++.a</code> (usually specifying
<code>-lsupc++</code> when calling g++ for the final link step will
do it). This library contains only those support routines, one per
object file. But if you are using anything from the rest of the
library, such as IOStreams or vectors, then you'll still need
pieces from <code>libstdc++.a</code>.

<p>The second method is one we hope to incorporate into the library
build process. Some platforms can place each function and variable
