Subject: [PATCH] testoverlay: Remove unused 'flip' variable.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The testoverlay SDL 1.2 test program has a variable 'flip' which is
never used. It seems to be intended to be used for double-buffering/page
flipping, but it's never read from after it's set.
This results in a warning being printed on gcc 10.3:
/home/david/Development/sdl12-compat/test/testoverlay.c: In function ‘main’:
/home/david/Development/sdl12-compat/test/testoverlay.c:324:6: warning: variable ‘flip’ set but not used [-Wunused-but-set-variable]
