bug#65727: 30.0.50; Build failure in MSYS2 when --with-native-compilation

[voi dfoo]

The dependency versions are not explicitly specified in my installation script 

"pacman -S --needed --noconfirm git zip base-devel mingw-w64-x86_64-autotools mingw-w64-x86_64-toolchain mingw-w64-x86_64-xpm-nox mingw-w64-x86_64-libtiff mingw-w64-x86_64-giflib mingw-w64-x86_64-libpng mingw-w64-x86_64-libjpeg-turbo mingw-w64-x86_64-librsvg mingw-w64-x86_64-libwebp mingw-w64-x86_64-lcms2 mingw-w64-x86_64-gnutls mingw-w64-x86_64-jansson mingw-w64-x86_64-libgccjit mingw-w64-x86_64-libxml2 mingw-w64-x86_64-gnutls mingw-w64-x86_64-zlib mingw-w64-x86_64-harfbuzz mingw-w64-x86_64-tree-sitter mingw-w64-x86_64-sqlite3"

There is a update of the package to gcc 13.2.0 that may be related: https://github.com/msys2/MINGW-packages/commits/master/mingw-w64-gcc

Did you per chance upgrade GCC and/or libgccjit and/or Binutils
between the last successful build and the first failed one?
