[Emacs-diffs] master 6cd5678: Clarify compiler-pacifier in frame.c

[Eli Zaretskii <eliz@gnu.org>]

I'm sorry, but how is this variant more clear than the previous one?

Please don't assume that I don't know about UNINIT or somehow forgot
it existed.  It is not true that the initializations are "unnecessary"
in this case, just that when geometry is non-zero, x and y are
initialized.  None of that is clear from the UNINIT kludge.  If we
want this to be abundantly clear, we should have a comment there to
the above effect.

      Clarify compiler-pacifier in frame.c

      * src/frame.c (Fx_parse_geometry): Pacify the compiler in a
      different way, so that the human reader can more easily see
      that the initializations are unnecessary.
