Re: [ANN] Lua 5.3.0 (rc3) now available

[Xavier Wang <weasley.wx@...>]

I have meet a strange issue with a modified one.c.

with standard build method, Lua 5.3 is okay without any warning. but
with one.c , it produce this warning:

D:\Work\Sources\lua-5.3.0\build>D:\mingw\bin\gcc -o lua52.exe -s -O2
-Wall -I../src one.c
In file included from one.c:51:0:
../src/lobject.c: In function 'luaO_tostring':

in format [-Wformat=]
     len = lua_integer2str(buff, ivalue(obj));
     ^
../src/lobject.c:327:5: warning: too many arguments for format
[-Wformat-extra-args]
In file included from one.c:73:0:
../src/liolib.c: In function 'g_write':
../src/liolib.c:610:17: warning: unknown conversion type character 'l'
in format [-Wformat=]
                 ? fprintf(f, LUA_INTEGER_FMT, lua_tointeger(L, arg))
                 ^
../src/liolib.c:610:17: warning: too many arguments for format
[-Wformat-extra-args]

D:\Work\Sources\lua-5.3.0\build>

BUT, with the same compiler (MInGW-w64, 4.8.3), use make mingw is all
okay, and just compile lobject.c is also okay, the warning only occurs
when using one.c.

the one.c is here:
