Bug ID: 24195
Summary: clang-cl should be compatible to cl.exe regarding
extern C handling in namespaces
Product: clang
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: C++
Assignee: [email protected]

Classification: Unclassified
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
