Re: [ANN] Lua 5.3.0 (work2) now available

build Lua 5.3.0 work2 with gcc -O3 -Wall produce this warning:

gcc -O3 -Wall -Wextra -DLUA_COMPAT_ALL -DLUA_BUILD_AS_DLL -c -o lvm.o lvm.c

lvm.c: In function 'luaV_equalobj':

lvm.c:223:22: warning: 'n2' may be used uninitialized in this function [-Wmaybe-uninitialized]

lua_Number n1, n2;

In file included from lua.h:16:0,

from lvm.c:16:

luaconf.h:511:30: warning: 'n1' may be used uninitialized in this function [-Wmaybe-uninitialized]

#define luai_numeq(a,b) ((a)==(b))

lvm.c:223:18: note: 'n1' was declared here

lua_Number n1, n2;

Is that worth to fix? (-O3 is unsafe optimize?)
