libretro-db Makefile fails (MINGGW64 Windows 11)

Following instructions from
https://github.com/libretro/RetroArch/blob/master/libretro-db/README.md

git clone https://github.com/libretro/libretro-super.git
cd libretro-super
./libretro-fetch.sh retroarch
cd retroarch
./configure
cd libretro-db
c_converter "NAME_OF_RDB_FILE.rdb" "NAME_OF_SOURCE_DAT.dat"

gives
bash: c_converter: command not found

So I try to run the Makefile and get the following

cc -I. -I../libretro-common/include rmsgpack.c -c -g -O2 -Wall -DNDEBUG -o rmsgpack.o
Makefile:55: recipe for target 'rmsgpack.o' failed
process_begin: CreateProcess(NULL, cc -I. -I../libretro-common/include rmsgpack.c -c -g -O2 -Wall -DNDEBUG -o rmsgpack.o, ...) failed.
make (e=2): The system cannot find the file specified.
make: *** [rmsgpack.o] Error 2

I also tried the ./libretro-build-database.sh script from /libretro-super and get the same error

tried make on the retroarch folder incase something wasn't complied and get this message

CC input/input_keymaps.c
input/input_keymaps.c:70:20: fatal error: dinput.h: No such file or directory
 #include <dinput.h>

Any idea what I am missing please?

Start with libretro-db/README.md and the libretro-db Makefile, then reproduce the c_converter build command under the reported MinGW64 setup. Check the reported compiler and dinput.h failures across libretro-db and input/input_keymaps.c; done means identifying the missing build prerequisite or documenting a reproducible Windows build fix.
