bug#51366: Pure storage overflow warning in *GNU Emacs* buffer when emacs@27.2 is invoked

[Calvin Heim]

Hi all,

The pure space overflow warning does not appear in emacs-next@28.0.50-0.2ea3466
on my i686 machine, so this bug will disappear when the emacs package 
definition catches up to emacs-next. 

Happy hacking,

Calvin
