// We define two convenient macros that can be used to suppress
// deprecated-warnings for a specific code block rather than a whole project.
// This macros would be useful when you need to call deprecated function for
// some reason (e.g., for backward compatibility) but don't want warnings.
//
// Example code:
//
// deprecated_function()  // warning
//
// FCL_SUPPRESS_DEPRECATED_BEGIN
// deprecated_function()  // okay, no warning
// FCL_SUPPRESS_DEPRECATED_END
//
