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
