Please distinguish carefully between MSYS and MinGW. MSYS (or MSYS2) programs runs on top of a copylefted compatibility DLL that is suspiciously similar to Cygwin. They must be GPL-compatible. MinGW programs link with MSVCRT. They are compiled by GCC toolchain programs, most of which are MSYS programs.
