Description Stefan Potyra 2010-07-16 18:36:22 UTC 
Hi,

thanks for your work!

as seen on libglib2.0-dev (2.24.0-0ubuntu1) on Ubuntu and on libglib2.0-dev (2.24.1-1) on Debian/unstable, just including <glib.h> when using -Wcast-qual will result in a warning.

(see Ubuntu's bug: https://bugs.launchpad.net/ubuntu/+source/glib2.0/+bug/554278 for more verbose information).

I'm not 100% sure if this is a duplicate of either 608137 or 600315, sorry if it is.

Cheers and thanks again for your work,
   Stefan.

It's a dup. And the solution is more-or-less "don't do that then"; -Wcast-qual generates false positives that can't always be worked around. (I'm not sure if it can be worked around in this particular case; AFAIK no one has tried.)

Sorry for the dupe (should I post there?)

I can understand the solution, but it's certainly sad for projects using glib, since that means they cannot use -Wcast-qual at all to find warnings *in the project*  (which might [and have proven to show for my case] be programming errors.).

Nonetheless thanks for your work and the quick response,
  Stefan.
