This gives the following warning in both Huge and Tiny (so I'm quoting
the Tiny log because the gcc command-line is shorter):

gcc -c -I. -Iproto -DHAVE_CONFIG_H     -O2 -fno-strength-reduce -Wall
-U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=1        -o objects/undo.o undo.c
undo.c: In function ‘undo_time’:
undo.c:2592:19: warning: ‘mark’ may be used uninitialized in this
function [-Wmaybe-uninitialized]
   if (uhp == NULL || uhp->uh_walk != mark)
                   ^


Best regards,
Tony.
