Right, and you can accomplish this simply by changing the
mingw target in src/Makefile to

mingw:
        $(MAKE) "LUA_A=lua51.dll" "LUA_T=lua.exe" "LUAC_T=luac.exe" \
        "AR=$(CC) -shared -Wl,--export-all-symbols -o" "RANLIB=strip --strip-unneeded" \
        "MYCFLAGS=-DLUA_BUILD_AS_DLL" "MYLIBS=" "MYLDFLAGS=-s" all
