Subject: Compiling with gcc -m32 on x86_64

Hi!

Is it expected that compiling as 32-bit on 64-bit will succeed?

I'm seeing "EXTRA_CFLAGS=-m32 make" bomb
in ext/opcache/zend_accelerator_util_funcs.c.

One problem I notice is that one definition of accel_xlat_get() takes one
argument, another takes two. (Source.
<https://github.com/php/php-src/blob/master/ext/opcache/zend_accelerator_util_funcs.c#L31>)
 Only the one argument version is used. (Source.
<https://github.com/php/php-src/blob/master/ext/opcache/zend_accelerator_util_funcs.c#L160>)
 The two argument version is never used. (And that second argument is
passed as the fourth formal argument and the return value
of zend_hash_str_find_ptr, which only takes 3 arguments and returns void.)

There are other problems though.  Before I go down this path, I wanted to
check if -m32 was meant to be used.

Thanks,
bishop
