clang compiling complex reports err

Clang Frontend
#1

If I use MSVC’s math.h, clang will report err I have formed a simple case to show it:

struct _complex {
double x,y;
} ;

#if SHOWERR
void foo( struct _complex _Complex) {
_Complex.x = 0;
}
#else
void foo( struct _complex cc) {
cc.x = 0;
}
#endif

int main()
{
struct _complex cc;
foo(cc);
}

clang aa.cpp -DSHOWERR=1

aa.cpp(7) : error: ‘_Complex struct’ is invalid
void foo( struct _complex _Complex) {
^

It seems _Complex is a reserved key word. Any suggestion?

Thanks

yes clang considers _Complex to be a reserved keyword, MSVC don’t. But _Complex is not in MSVC headers, it is in your cod right?
So you can rename that variable. Otherwise feel free to submit a PR or a patch.

We had the same problem with the _Bool keyword.
