Hi Reid, Attached is a patch to handle a corner case supported by MSVC. I decided to attempt to workaround the behaviour in clang after encountering it in public MS headers for XAudio where clang would fail to generate a valid UUID due to the UUID components being combined with the '-' UUID separators. Clang was attempting to recover but would preserve the leading whitespace from the tokens after each failed paste leading to spaces creeping into the UUID and causing an error in the __declspace(uuid()) parsing.
Reference: Microsoft DirectX SDK (June 2010)\Include\XAudio2.h(51) Test case included and tested against latest trunk. Let me know if it looks acceptable! Cheers, Will.
