<p>All parallel algorithms are intended to have signatures that are
equivalent to the ISO C++ algorithms replaced. For instance, the
<code>std::adjacent_find</code> function is declared as:
-
+</p>
<pre>
namespace std
{
}
</pre>
+<p>
Which means that there should be something equivalent for the parallel
version. Indeed, this is the case:
+</p>
<pre>
namespace std
<p> Putting all this together, the general view of overloads for the
parallel algorithms look like this:
-<p>
+</p>
<ul>
<li>ISO C++ signature</li>
<li>ISO C++ signature + sequential_tag argument</li>
</pre>

Example flags to pass down for various embedded builds are as follows:
<pre>
--target=powerpc-eabism (libgloss/sim)
-make check-target-libstdc++ RUNTESTFLAGS="--target_board=powerpc-sim"
+make check-target-libstdc++-v3 RUNTESTFLAGS="--target_board=powerpc-sim"

If your GCC source tree is at <code>/path/to/gcc</code>, then you can
run the tests as follows:

The testsuite will create a number of files in the directory in which you
run this command,. Some of those files might use the same name as
files created by other testsuites (like the ones for GCC and G++), so
