Bug#951507: wine: please fix arm64 build failure with some gcc versions

Source: wine
version: 5.0-2
Severity: normal
Tags: patch


Hello, looks like wine is still failing on Ubuntu arm64, probably because of new gcc or new glibc, or a combo of them both...

        ~~ ^ ~
looks like the following trivial patch is enough to make it compile correctly

(we could also export -Wno-tautological-unsigned-enum-zero-compare to fix it but the bug seems real)

thanks for considering it!
