Not with gcc 3.4.2 on Solaris 9/sparc -- maybe you're thinking of
sizeof(long).
% cat foo.c
#include <stdio.h>
int
main(void)
{
printf("sizeof(void *) = %d\n", sizeof(void *));
printf("sizeof(int) = %d\n", sizeof(int));
printf("sizeof(long) = %d\n", sizeof(long));
return 0;
}
% gcc -m32 -o foo foo.c
% ./foo
sizeof(void *) = 4
sizeof(int) = 4
sizeof(long) = 4
% gcc -m64 -o foo foo.c
% ./foo
sizeof(void *) = 8
sizeof(int) = 4
sizeof(long) = 8
