I'm pretty sure I have my arms around this one.
Two questions:
1. Any ideas on how to make testsuite cases? Any examples of looking at
preprocessed files in the testsuite?
2. Assuming this gets into mainline, how far can we backport?

Please send your patches, questions, etc, about this and the other bug to the
mailing list, with Jason in CC, otherwise we seriously risk unnecessarily
delaying the resolution of the issues.

What about multi-char constants, or are they not permitted in C++ UDLs?
Normally they get converted to int, so they're not *meaningful*, but ...
Also, remember the different prefixes: L for wchar_t, u8 for char-but-utf8, u
for char16_t, and U for char32_t
unsigned int fourcc = 'ABCD';
