[Emacs-diffs] master 288e1fd 2/4: Port to 32-bit Sun C 5.12 sparc

[Paul Eggert]

branch: master
commit 288e1fd737265b7fc20c2c0d5a7b4ffaf26ecf66
Author: Paul Eggert <address@hidden>
Commit: Paul Eggert <address@hidden>

    Port to 32-bit Sun C 5.12 sparc
    
    * make-docfile.c (close_emacs_globals): Align lispsym to GCALIGNMENT.
    The alignment is required on all platforms; it just happens to have
    been properly aligned on the previous platforms we tested.
