I should also of confessed...that it only worked after I had fixed my
example program
clang-tidy Stdio.cxx -- -I"c:/Program Files (x86)/Microsoft Visual Studio
12.0/VC/INCLUDE" -fms-extensions -fms-compatibility
-fms-compatibility-version=18 -std=c++11 -D_M_X64
D:\buildareas\HEAD\issdev\src\test\tidy\Stdio.cxx:3:1: error: 'main' must
return 'int' [clang-diagnostic-error]
void main(int argc,char **argv)
^
int
D:\buildareas\HEAD\issdev\src\test\tidy\Stdio.cxx:6:4: error: void function
'main' should not return a value [clang-diagnostic-return-type]
return 0;
