Full log of the build (gzip because of size)

Hi,
when compiling wine from up to date sources (taken from Gitlab today
2025-05-13)
I get a few warnings (see wine-build-full.log.gz)

This is how I build it:

CFLAGS="-march=native -O3 -pipe -fno-plt -fexceptions \
        -Wp,-D_FORTIFY_SOURCE=3 -Wformat -Werror=format-security \
        -fstack-clash-protection -fcf-protection -ffat-lto-objects"
CXXFLAGS="$CFLAGS -Wp,-D_GLIBCXX_ASSERTIONS"
LDFLAGS="-Wl,-O1 -Wl,--sort-common -Wl,--as-needed -Wl,-z,relro -Wl,-z,now \
         -Wl,-z,pack-relative-relocs"
  # Apply flags for cross-compilation
  export CROSSCFLAGS="-O2 -pipe -g"
  export CROSSCXXFLAGS="-O2 -pipe -g"
  export CROSSLDFLAGS="-Wl,-O1"

../wine/configure \
    --prefix=/usr \
    --libdir=/usr/lib \
    --with-x \
    --with-wayland \
    --with-gstreamer \
    --enable-win64
make
  ../wine/configure \
    --prefix=/usr \
    --libdir=/usr/lib \
    --with-x \
    --with-wayland \
    --with-gstreamer \
    --with-wine64="$srcdir/$pkgname-64-build"
make

Made the following greps to have more focused logs (thought it might help):
grep -C 5 "note: " wine-build-full.log > wine-build-grepped-notes.log
grep -C 5 "warning: " wine-build-full.log > wine-build-grepped-warnings.log
(full log is called wine-build-full.log.gz)

Thank you for your help!
