<dd><p>In 3.4 and later, tries to turn on the generation of
stdc++.h.gch, a pre-compiled file including all the standard
C++ includes. If enabled (as by default), and the compiler
seems capable of passing the simple sanity checks thrown at
it, try to build stdc++.h.gch as part of the make process.
In addition, this generated file is used later on (by appending <code>
--include bits/stdc++.h </code> to CXXFLAGS) when running the
testsuite.
