<pre>If you try to compile this code with -std=c++11, __DATE__ and __TIME__ macros
will be treated as user-defined literals. These macros are expanded correctly
for older standard.
const char* s = "Build "__DATE__" at "__TIME__" ";
Also note this comment in clang/lib/Lex/Lexer.cpp, line 1657. Why ud-suffix
takes precedence over macro? Macro should be expanded first.
// them. We assume a suffix beginning with a UCN or UTF-8 character is more
// likely to be a ud-suffix than a macro, however, and accept that.</pre>
