// config_os.h - written and placed in public domain by Jeffrey Walton
// the bits that make up this source file are from the
// library's monolithic config.h.
/// \file config_os.h
/// \brief Library configuration file
/// \details <tt>config.h</tt> was split into components in May 2019 to better
/// integrate with Autoconf and its feature tests. The splitting occured so
/// users could continue to include <tt>config.h</tt> while allowing Autoconf
/// to write new <tt>config_asm.h</tt> and new <tt>config_cxx.h</tt> using
/// its feature tests.
/// \sa <A HREF="https://github.com/weidai11/cryptopp/issues/835">Issue 835</A>
/// \since Crypto++ 8.3
