+Subject: [PATCH] perl: Replace -w option in shebangs with modern "use
+ warnings"
+
+In some builds we might provide ac_cv_path_PERL as /usr/bin/env perl
+to use newer version of the perl from users PATH rather than
+older from standard system path.
+
+However using /usr/bin/env perl -w from shebang line isn't
+possible because it translates to something like
+/usr/bin/env -w perl and env complains about illegal option.
+
+To address this we can remove -w option from perl shebang
+line and add "use warnings" statement.
+
