Trying to build chicken on windows (11) in the msys2 environment

Hello list

At work on a windows computer I installed the MSYS2 package,
as described at https://www.msys2.org/

Installed the tool chain according to the description at
http://wiki.call-cc.org/msys2 (copy paste the pacman command).

Downloaded the chicken tar ball
https://code.call-cc.org/releases/5.4.0/chicken-5.4.0.tar.gz

Unpack and cd into the chicken directory.

During compilation I get errors. Here is the make call and the output

$ make PLATFORM=mingw-msys PREFIX=C:/msys64/usr/local/
