+Subject: [PATCH libX11] cpprules.in: squash whitespace in generated files
+
+CPP is used to generate files, but as cpp reads files from the build host the
+output has a number of blank lines at the beginning which varies depending on
+what GCC and friends is used.
+
+Pathalogical example:
+
+ $ cpp -undef -traditional /dev/null
+ # 1 "/dev/null"
+ # 1 "<built-in>"
+ # 1 "<command-line>"
+ # 31 "<command-line>"
+ # 1 "/usr/include/stdc-predef.h" 1 3 4
+
+ # 17 "/usr/include/stdc-predef.h" 3 4
+
+ [ 40 blank line ]
+
+ # 32 "<command-line>" 2
+ # 1 "/dev/null"
+
+So depending on the content of stdc-predef.h and what other headers CPP will
+load, the amount of whitespace in the generates files varies. This can result in
+differences in reproducible environments, and file conflicts in multilib
+environments.
+
+As whitespace is irrelevant to these machine-readable files, extend the sed to
+just delete blank lines.
