Description Damjan Jovanovic 2023-05-12 01:27:51 UTC 
Not currently a problem in the Port as we pass "--disable-tests" to ./configure, but without that switch Wine won't build with Clang, because some unit tests require the compiler to have a built-in "llabs", and Clang doesn't provide it:

lld-link: error: undefined symbol: __declspec(dllimport) _llabs

Upstream issue was closed invalid in 2011:

This unrelated project had an internal workaround, not using llabs on MSVC < 18:

Hi Damjan,

Can you provide a patch for wine-devel that uses that #define so we workaround the problem with clang?
