Recompile Mame 2003 with disabled disclaimer and gameinfo

Hello I’m trying to recompile Mame 2003 core on Linux with disabled disclaimer and game info. I see in file osd.c these lines:

    int     skip_disclaimer;    /* 1 to skip the disclaimer screen at startup */
    int     skip_gameinfo;        /* 1 to skip the game info screen at startup */

I tried adding 1 and recompiling but with no changes:

    int 1    skip_disclaimer;    /* 1 to skip the disclaimer screen at startup */
    int 1    skip_gameinfo;        /* 1 to skip the game info screen at startup */

Does anyone know if this can be achieved and how? Thank you

I have never programmed in C but based on http://www.techonthenet.com/c_language/variables/create_int.php I’d suggest int 1 skip_disclaimer = 1; int 1 skip_gameinfo = 1;

It doesn’t work. I also tried:

int skip_disclaimer = 1; 
int skip_gameinfo = 1;

but it’s still the same. Disclaimer and game info is always shown.
