+Subject: [PATCH] Adapt to perl 5.37.1
+
+Perl 5.37.1 removed a deprecated sv_nv() macro and SDL fails to build
+with Perl 5.38.0:
+
+lib/SDLx/Controller/Interface.xs:60:26: error: implicit declaration of function 'sv_nv'
+   60 |         out->dv_x      = sv_nv(temp);
+      |                          ^~~~~
+
+Users are advised to use SvNVx() macro instead. SvNVx() seems to have been
+available all the time (it predates a commit from 1993-10-07).
+
+This patch does that.
