[PATCH] Skip preprocessor directives in mklog

[PATCH] Skip preprocessor directives in mklog

[Yury Gribov]

[-- Attachment #1: Type: text/plain, Size: 245 bytes --]

Hi all,

Contrib/mklog is currently faked by preprocessor directives inside 
functions to produce invalid ChangeLog.  The attached patch fixes this.

Tested with my local mklog testsuite and http://paste.debian.net/167999/ 
.  Ok to commit?

Hi Yury,

The effect of the patch on the mklog output using the pastebin input is:

The patch looks fine to me.

I'm not really involved in GCC development anymore. I would suggest
that this script should be maintained by whoever's been hacking on it
the most. It's a simple script, so it shouldn't be hard to find a new
maintainer for it.

Trevor, Tom,

Does anyone want to volunteer?

I'm not a good choice to be the maintainer of a perl script. I have very limited 
knowledge of it, and look at perl code maybe once per year. So I'm 
unvolunteering myself.

Thanks,

I'm all kinds of sorry about the original choice of scripting
language. I'd just spend a couple of hours re-writing it in python.

I think you'd be the best choice :)

 I read about as much perl as Tom, but given you've tested it and it
 seems sane I'll say ok if you want me to.

thanks!

Hm, looks like I'm the only one who perls here.  What should I do to 
become a maintainer?

Going to trust you on this one since I don't think anyone else does much 
with perl.
