Dear Maintainer,

When started, emacs-gtk (Bullseye, testing) shows a window beginning

Warning Warning!!!  Pure space overflow    !!!Warning Warning
(See the node Pure Storage in the Lisp manual for details.)

followed by the standard emacs Help window stuff.

The node Pure Storage in the Lisp manual says
" ... Emacs will display a warning about the overflow when it starts.  If
  this happens, you should increase the compilation parameter
  SYSTEM_PURESIZE_EXTRA  in the file src/puresize.h and rebuild
  Emacs."

I do not know what the implications of Pure Space overflow are but presumably
bad things happen in some circumstances.  However emacs is working for me
so I suppose the circumstances are not all that common.

Still, the fix is straightforward (apparently) so well worth doing, IMHO

Dear Maintainer,

This issue was reported in bullseye testing for a previous version of
the package.  Perhaps this message is redundant but it's just to
confirm that the issue is still present in bullseye stable (for i386,
not for amd64).  Here are the contents of the emacs startup screen
showing the warning at the top and the build details at the bottom:
