<pre>Hello,
I try to use libclang to parse some source files. But the error is also visible
in clang-cl (r242653 nightly build).
The error originates from boost interprocess headers which declare windows.h
functions different than windows.h. The error got a work-around in later boost
versions but unfortunately we are stuck with 1.50 for a while.
It boils down to Visual Studio Compiler accepting the following, but clang-cl
does not:
extern "C" void foo(int a);
namespace bar {
extern "C" void foo(long b);
}
In the boost case the functions get pointers to different structures.
Could you modify clang to accept this oddity with enabled ms-extensions /
ms-compatibility like cl.exe does?
Thanks,
Gregor</pre>
