Yet another quick test:

-8<-----------------------------------
minotaur:/tmp> cat sizes.c
#include <stdio.h>

int main(int argc, char **argv)
{
   printf("A long long is %d bytes\n", sizeof(long long));
   printf("A long is %d bytes\n", sizeof(long));
   printf("An int is %d bytes\n", sizeof(int));
   printf("A short is %d bytes\n", sizeof(short));
   printf("A char is %d bytes\n", sizeof(char));
   return 0;
}
minotaur:/tmp> gcc -o sizes sizes.c
minotaur:/tmp> file sizes
sizes: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically 
linked (uses shared libs), not stripped
minotaur:/tmp> ./sizes
A long long is 8 bytes
A long is 8 bytes
An int is 4 bytes
A short is 2 bytes
A char is 1 bytes
-8<-----------------------------------

I am not aware of any switches which changes this behaviour, but google 
is your friend...
