Reproduction
I know clang-cl ain't a bug-to-bug compatible driver, though, from my
understanding it does try to accept the windows headers.
The following case is reduced from sqloledb.h, which can be found in C:\Program
Files (x86)\Windows Kits\10\Include\<version>\um
This has a: extern Struct Name = {0x00, 0x00 ...};
Followed by: extern "C" Struct Name;
Somehow, VS2015 seems to accept this, while clang-cl 4.0-rc2 doesn't.
In attachment you can find the cpp file, compile commands, clang-output and
MSVC obj file</pre>
