Description:
------------
I am compiling the PHP-4.3.11 on Tru64 . So I exclueded the php-4.3.11/win32 directory. When I try to build the source I get the error saying 

php4/main/php_ini.c, line 34: Cannot find file "win32/php_registry.h" specified in #include directive. (noinclfilef)
#include "win32/php_registry.h"
-^

When I looked into php4/main/php_ini.c file I noticed that none of the functions mentioned in "win32/php_registry.h" are utilised in this file. So when I take out this include directory The compilation goes out smooth.

Reproduce code:
---------------
21  /* Check CWD for php.ini */
    22  #define INI_CHECK_CWD
    23
    24  #include "php.h"
    25  #include "ext/standard/info.h"
    26  #include "zend_ini.h"
    27  #include "php_ini.h"
    28  #include "ext/standard/dl.h"
    29  #include "zend_extensions.h"
    30  #include "zend_highlight.h"
    31  #include "SAPI.h"
    32  #include "php_main.h"
    33  #include "php_scandir.h"
    34  #include "win32/php_registry.h"
    35
    36  #if HAVE_SCANDIR && HAVE_ALPHASORT && HAVE_DIRENT_H


Expected result:
----------------
The compilation should go smooth if win32 directory is excluded

Actual result:
--------------
Getting Compilation error
