Why some uplong were replaced by uintptr_t?

Oups, that must have been me. However the commit break my link:

% cat needed_brace.c
#include <stdio.h>

static void func();

int main(int argc, char **argv)
{
        static struct s {
                void (*elem)();
        } t[] = {
                {func}        /* tcc requires these braces! (see 6.7.8 
"Initialization" §16-17) */
        };

        printf("func is %p, t[0].func is %p\n", func, t[0].elem);
        return 0;
}

static void func()
{
        int x = 1;
        x++;
}

% tcc -o needed_brace needed_brace.c
tcc: error: undefined symbol '__libc_csu_fini'
tcc: error: undefined symbol '__libc_csu_init'
tcc: error: undefined symbol '__libc_start_main'
tcc: error: undefined symbol 'printf'
zsh: exit 1     tcc -o needed_brace needed_brace.c

It seems the rewriting in Makefile wasn't right.
