<pre>A recent change (<a href="https://reviews.llvm.org/rL323490">https://reviews.llvm.org/rL323490</a>) added support for the MS
Windows platforms to include the C math.h header as the first thing in the C++
math.h. This creates a problem for C libraries that require some configuration
to provide the correct functionality for libc++.
Such configuration could be done in __config before, but now there is no such
place. Can we move __config to be included before the C math.h?</pre>
