Sample of the build log

Greetings,

I have been building quite a few Wine versions in the past on the same build
system (with gcc as the system compiler, and clang available as a secondary
compiler), and everything always went fine until Wine v6.16 came out: with the
latter, for some (weird) reason, the build system seems to use *both* gcc and
clang to compile Wine, and fails as a result...

Specifying 'export CC=gcc;export CXX=g++' does not suffice to prevent Wine's
build system to wrongly pick up clang, and I must uninstall the latter to get
Wine v6.16 to build successfully with gcc...

Attached is a short sample of the build log (at the point where it fails too)
for you to see.
