Subject: * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
X-Git-Tag: emacs-pretest-24.0.90~104^2~275^2~394^2~17
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=b25d760e185c85e190402eddd0d756ddc014a58c;p=emacs.git

* coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.

This avoids several warnings with gcc -Wstrict-overflow.
