/*
 * Note [Symbols for MinGW's printf]
 * ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 *
 * The printf offered by Microsoft's libc implementation, msvcrt, is quite
 * incomplete, lacking support for even %ull. Consequently mingw-w64 offers its
 * own implementation which we enable. However, to be thread-safe the
 * implementation uses _lock_file. This would be fine except msvcrt.dll doesn't
 * export _lock_file, only numbered versions do (e.g. msvcrt90.dll).
 *
 * To work around this mingw-w64 packages a static archive of msvcrt which
 * includes their own implementation of _lock_file. However, this means that
 * the archive contains things which the dynamic library does not; consequently
 * we need to ensure that the runtime linker provides this symbol.
 *
 * It's all just so terrible.
 *
 * See also:

/* Note [_iob_func symbol]
 * ~~~~~~~~~~~~~~~~~~~~~~~
 *
 * Microsoft in VS2013 to VS2015 transition made a backwards incompatible change
 * to the stdio function __iob_func.
 *
 * They used to be defined as:
 *
 * #define stdin  (&__iob_func()[0])
 * #define stdout (&__iob_func()[1])
 * #define stderr (&__iob_func()[2])
 *
 * whereas now they're defined as:
 *
 * #define stdin  (__acrt_iob_func(0))
 * #define stdout (__acrt_iob_func(1))
 * #define stderr (__acrt_iob_func(2))
 *
 * Mingw-w64 followed along with the madness and so we have to deal with both
 * version of these symbols.
 *
 * As such when you mix new and old libraries you get a missing symbols error
 * for __acrt_iob_func.  It then links against the PLT for the function but that
 * no longer exists.  Instead we forward the request for the PLT symbol to the
 * symbol directly which is defined inline since we're using a newer compiler.
 *
 * See also:
 * https://docs.microsoft.com/en-us/cpp/porting/visual-cpp-change-history-2003-2015?view=vs-2017#stdioh-and-conioh
