I’ve run a cross-bootstrap, but not a bootstrap on > Windows, nor have I run the test suite on Windows. Cross compilers don't bootstrap (build themselves multiple times), only build. Sure, I have built a cross compiler to write and verify this change too, but I have no access to Windows to bootstrap/regtest it natively. As I said on gcc-patches, it is highly unlikely it will regress something, because if it doesn't crash in the newly added condition, then it partially reverts to the January state.
