Tristan,
   If you follow the thread starting at...

http://gcc.gnu.org/ml/gcc-patches/2009-08/msg01629.html

you will see other platforms like AIX are concerned as well.
The best answer I have read so far...

http://gcc.gnu.org/ml/gcc-patches/2009-08/msg01656.html

...suggests that FSF gcc will 'try' to maintain compatibility
in the generated debug code but may not go out of their way
to keep hacks to work around bugs in the older version of
gdb.
