Patch from https://github.com/shlomif/perl-XML-LibXSLT/commit/40fdc7f0.patch
From 40fdc7f0443949d9556f0ecf15eb7777d543cee1 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Avoid C implicit function declaration in Makefile.PL (C99
compat)
Future compilers are likely not to support implicit function
declarations. Add a fake prototype so that the probes will
not always fail with such compilers.
