Thanks, should be fixed after https://github.com/boostorg/winapi/commit/c4ebb6d9d0f274cfbdf50c456a7a17cdc1419d7d.

Confirmed.

Confirmed. I use the |LP64| macro to detect Cygwin 64 by the way, if that helps.

__LP64__ is a general macro that indicates platform with LP64 convention (i.e. with 64-bit long). It is defined on 64-bit Linux, for example.

Yes I know. I also know (now) that you already use __LP64__, which is why I edited it out.
