- Subject: [PATCH 2/2] Prefer response files over linker scripts for mingw tools
- The GCC/binutils tools support response files just fine, while
- lld (impersonating GNU ld) only supports response files, not
- linker scripts. Using a linker script as input just to pass a
- list of files is overkill for cases when a response file is enough.
