Change Details

In Debian buster /usr/share/doc/gcc-mingw-w64-base/NEWS.Debian.gz says: > * This release of gcc-mingw-w64 changes the 32-bit exception handling > mechanism from SJLJ to Dwarf2, to match MSYS2, Fedora, and other > toolchains, and to allow the Rust toolchain to provide 32-bit > cross-compilers. > This will require rebuilding all artifacts built with previous > releases of the toolchain. Shared binaries will need to be shipped > with the dw2 DLL instead of the sjlj DLL. IIUC, we use SJLJ exception for GnuPG and its friends now.
