Description:
------------
When compiling 4.3.10 on 64-bit Intel architecture, we get:

/usr/local/tarballs/php-4.3.10/ext/standard/exec.c: In function `proc_open_rsrc_dtor':
/usr/local/tarballs/php-4.3.10/ext/standard/exec.c:611: warning: cast from pointer to integer of different size

i.e.:


static void proc_open_rsrc_dtor(zend_rsrc_list_entry *rsrc TSRMLS_DC)
{
#ifdef PHP_WIN32
    HANDLE child;
    DWORD wstatus;

    child = (HANDLE)rsrc->ptr;
    WaitForSingleObject(child, INFINITE);
    GetExitCodeProcess(child, &wstatus);
    FG(pclose_ret) = wstatus;
    CloseHandle(child);
#else
# if HAVE_SYS_WAIT_H
    int wstatus;
    pid_t child, wait_pid;

    child = (pid_t)rsrc->ptr; <--------- HERE

    do {
        wait_pid = waitpid(child, &wstatus, 0);
    } while (wait_pid == -1 && errno == EINTR);

    if (wait_pid == -1)
        FG(pclose_ret) = -1;
    else {
        if (WIFEXITED(wstatus))
            wstatus = WEXITSTATUS(wstatus);
        FG(pclose_ret) = wstatus;
    }
    ....


Probably nothing, and probably related to

Tested on php4-STABLE-200503040930. 

Error still occurs, which is not surprising as the
code did not change.

Here is the complete list of warnings btw:


/usr/local/tarballs/php4-STABLE-200503040930/ext/standard/exec.c: In function `proc_open_rsrc_dtor':
/usr/local/tarballs/php4-STABLE-200503040930/ext/standard/exec.c:611: warning: cast from pointer to integer of different size
