Hi
Attached patch fixes the following compilation warnings with
clang-3.5 (trunk in svn) when compiling vim tiny 7.4.183:
ex_cmds.c:4102:14: warning: variable 'bigness' is used uninitialized
whenever 'if' condition is false
[-Wsometimes-uninitialized]
else if (firstwin == lastwin)
^~~~~~~~~~~~~~~~~~~
./globals.h:552:19: note: expanded from macro 'firstwin'
# define firstwin curwin
^
ex_cmds.c:4108:9: note: uninitialized use occurs here
if (bigness < 1)
^~~~~~~
ex_cmds.c:4102:10: note: remove the 'if' if its condition is always true
else if (firstwin == lastwin)
^~~~~~~~~~~~~~~~~~~~~~~~
ex_cmds.c:4091:17: note: initialize the variable 'bigness' to silence
this warning
int bigness;
^
= 0
Regards
Dominique
