Hi,

The following is a reduced test case from trying to compile RapidJSON (as part
of a MySQL build) on Windows. I'm not sure if the original (unreduced) code was
valid or not, but in any case, the compiler shouldn't assert-fail :-)

$ cat pragma.cc
_Pragma("GCC diagnostic") _Pragma("GCC diagnostic")

R:\ade\mysql\obj>"C:\Program Files\LLVM\msbuild-bin\CL.exe" h:\pragma.cc
