The configure script concludes that Perl extension XS cannot be built:

I cannote figure out why it reaches this conclusion: the TestXS module
is built successfully. How can I find out why the detection fails?
I ran into that at first, too. In short:
pacman mingw-w64-{i686,x86_64}-perl
fixed it for me.
The crucial output appears on the terminal only, with nothing useful in
config.log. It's a missing <sys/wait.h> which the perl5 CORE/perl.h is
trying to access in the test compile performed by configure (log excerpt
attached), lead by CORE/config.h which claims it should be available.
But there is not <sys/wait.h> among Min's headers --- there's one in
MSys2. That pointed me to the solution: you need to have _MinGW_
edition(s) of Perl installed, not just MSys2's own one, to build the XS
stuff.
