Building php-pcre extension on windows

PHP experts everywhere!! I am building PHP 5.1.2 on windows without pcre-regex extension. I am building building pcre independently and then I am building the extension php_pcre.dll. I build few other extensions too. I keep the extensions in c:\php\extensions which is set in php.ini. I am getting an error that php_pcre.dll extension is invalid or corrupt whenever php call is being invoked. I believe I am not building php_pcre.dll extension properly, although any insights as to what could be the problem. Also is OK to build php --without-pcre-regex extension at all?
