I tried to build libtiff on MSYS2+minGW but found an interruption..
 

When I tried to build libtiff on MSYS2+minGW and opened the MSYS2 shell, got error:

$ ./configure

configure: loading site script /etc/config.site
checking build system type... Invalid configuration `x86_64-pc-msys': system `msys' not recognized
configure: error: /bin/sh config/config.sub x86_64-pc-msys failed


Can I just override the environment var:

MSYSTEM_CHOST="x86_64-pc-msys"

with the correct one ?
What is the correct one to help me solving it ?.. Thanks much in advance..

Have a look at the output of
