+Subject: [PATCH 1/2] enc2xs: Add environment variable to suppress comments
+
+Comment generation in enc2xs can now be suppressed by setting the
+ENC2XS_NO_COMMENTS environment variable. This allows enc2xs to produce
+reproducible output by omitting the name of the generating program.

+Subject: [PATCH 2/2] Constant: Fix up shebang
+
+The instructions indicate that the script should be explicitly passed to
+"perl -x", so automatically setting the #! to be ^X is unnecessary and
+makes the file non-reproducible when building because ^X could be the
+absolute path to miniperl.
