7Subject: [PATCH libX11] cpprules.in: squash whitespace in generated files
8
9CPP is used to generate files, but as cpp reads files from the build host the
10output has a number of blank lines at the beginning which varies depending on
11what GCC and friends is used.
12
13Pathalogical example:
14
15 $ cpp -undef -traditional /dev/null
16 # 1 "/dev/null"
17 # 1 "<built-in>"
18 # 1 "<command-line>"
19 # 31 "<command-line>"
20 # 1 "/usr/include/stdc-predef.h" 1 3 4
21
22 # 17 "/usr/include/stdc-predef.h" 3 4
23
24 [ 40 blank line ]
25
26 # 32 "<command-line>" 2
27 # 1 "/dev/null"
28
29So depending on the content of stdc-predef.h and what other headers CPP will
30load, the amount of whitespace in the generates files varies. This can result in
31differences in reproducible environments, and file conflicts in multilib
32environments.
33
34As whitespace is irrelevant to these machine-readable files, extend the sed to
35just delete blank lines.
