This problem should occur for any platform that doesn't differentiate
long doublefromdoubleright?I think that rather than differentiating this on
os(Windows), we want to use something to differentiate this based onsizeof(long double) == sizeof(double).There was a problem hiding this comment.

Not exactly. This also requires another condition: the way the Windows headers declare it. This doesn't occur and the following reproducer test doesn't err on macos because the macos C++ header imports the C remquo into the std namespace for C++ rather than declaring another remquo for long double that would cause an overload with C remquo for long in Swift. I added text on it in the bug description here. So I think this is specific to Windows.
