+Subject: [PATCH 1/2] replace "perl -w" with "use warnings"
+
+The shebang's max length is usually 128 as defined in
+/usr/include/linux/binfmts.h:
+  #define BINPRM_BUF_SIZE 128
+
+There would be errors when @PERL@ is longer than 128, use
+'/usr/bin/env perl' can fix the problem, but '/usr/bin/env perl -w'
+doesn't work:
+
+/usr/bin/env: perl -w: No such file or directory
+
+So replace "perl -w" with "use warnings" to make it work.
