[php-src] Issue #12630: Windows: Duplicate "Unable to load dynamic library" warning

Issue: https://github.com/php/php-src/issues/12630 Author: staabm ### Description The following code: ```php $ php -v PHP Warning: PHP Startup: Unable to load dynamic library 'ftp' (tried: ext\ftp (Das angegebene Modul wurde nicht gefunden), ext\php_ftp.dll (Falscher Parameter)) in Unknown on line 0 Warning: PHP Startup: Unable to load dynamic library 'ftp' (tried: ext\ftp (Das angegebene Modul wurde nicht gefunden), ext\php_ftp.dll (Falscher Parameter)) in Unknown on line 0 PHP 8.2.12 (cli) (built: Oct 24 2023 21:15:35) (NTS Visual C++ 2019 x64) Copyright (c) The PHP Group Zend Engine v4.2.12, Copyright (c) Zend Technologies $ php -v 2>/dev/null Warning: PHP Startup: Unable to load dynamic library 'ftp' (tried: ext\ftp (Das angegebene Modul wurde nicht gefunden), ext\php_ftp.dll (Falscher Parameter)) in Unknown on line 0 PHP 8.2.12 (cli) (built: Oct 24 2023 21:15:35) (NTS Visual C++ 2019 x64) Copyright (c) The PHP Group Zend Engine v4.2.12, Copyright (c) Zend Technologies ``` But I expected this output instead: -> no warning in the output when stderr is redirected -> one error is propery redirected but it seems the very same error is emitted a second time on stdout? ### PHP Version 8.2.12 ### Operating System windows11
