On the failed images test:

program test_image_status

Write to a string and test the results.

I assume you have regression tested this again as stated in the earlier

[libstdc++,doc] Standardize references to Boost documentation

2017-02-12 Thread Gerald Pfeifer

It appears we have been using various ways to refer to bits of Boost
documentation, and I suggest to standardize this a bit per the patch
below.

http://www.boost.org/libs/ seems to be the shortest and
simplest form doing to.

Thoughts?

Ah, thanks for the reminder.

First, here's a patch to collate the existing list, ok?


Oh, definitely.  This makes sense, and I trust your sorting
skills. :-)

You mean, moving them to "Inactive Development Branches"?  Yes,
that makes sense.

New Swedish PO file for 'gcc' (version 7.1-b20170101)

2017-02-12 Thread Translation Project Robot

Hello, gentle maintainer.

This is a message from the Translation Project robot.

A revised PO file for textual domain 'gcc' has been submitted
by the Swedish team of translators.  The file is available at:

http://translationproject.org/latest/gcc/sv.po

(This file, 'gcc-7.1-b20170101.sv.po', has just now been sent to you in
a separate email.)

All other PO files for your package are available in:

http://translationproject.org/latest/gcc/

Please consider including all of these in your next release, whether
official or a pretest.

Whenever you have a new distribution with a new version number ready,
containing a newer POT file, please send the URL of that distribution
tarball to the address below.  The tarball may be just a pretest or a
snapshot, it does not even have to compile.  It is just used by the
translators when they need some extra translation context.

The following HTML page has been updated:

http://translationproject.org/domain/gcc.html

If any question arises, please contact the translation coordinator.

Thank you for all your work,

The Translation Project robot, in the
name of your translation coordinator.

Re: [PATCH doc] update -dM to mention excluded macros (PR 41540)

+The predefined macros @code{__FILE__}, @code{__LINE__}, @code{__DATE__},
+and @code{__TIME__} are excluded from this list because their replacements
+may change from one line of output to the next.

Is this ("their replacements may change") truefor __FILE__ as well?

In any case, this may be too nit-picking, and the patch looks fine
to me.

This has two instances of "the following examples".  Perhaps omit
the second instance and break the sentence, putting "G++ used to

explanation after the examples?

Also you'll need to write "-" instead of "->", and member
the second time as well (or member which we use in other places

This is fine with those changes, thanks.
