[gentoo-dev] Crossdev / glib news item

Hi, 

I volunteered to help Diego summarize a news item on "crossdev, glib and 
binary compatibility", see http://blog.flameeyes.eu/2011/05/15/
Here's the result; as I am neither a specialist in the topic nor know much 
about news items, please be lenient :)

--------------
If you are cross-compiling to a 32-bit architecture such as ARM, or if 
you are using a 32-bit architecture and have sys-devel/crossdev installed,
please be warned that - unless you follow the advice below - your system
may become seriously broken.

We have recently fixed bug 367351 in sys-devel/crossdev, where the size of 
the pthread_mutex_t type was hardwired incorrectly into configure scripts.
Unfortunately, if the size was incorrect before, switching to the correct
value changes the ABI of libgthread. All binaries linked against the previous
glib may thus simply crash. 

You will have to ensure the ABI stability before upgrading crossdev.
Information on how to fix this is available at the following URL:
  http://blog.flameeyes.eu/2011/05/15/
---------------

Opinions?

Cheers, 
Andreas

I think it would be a good idea to simply copy the instructions here,
rather than pointing at my blog.

Also, we need to to cut down on the actual versions the problem is
present on, so that we can give a good idea to our users. As far as I
can tell, the 0.9 series is not involved, so it shouldn't require
rebuild if that's used.

Comments from the others?

Please post the full news item with headers. For example the filter
headers are quite central.

i really dont think crossdev merits a news item considering its general 
support status and the likely hood of actual users who are affected by this
