ext/filter, custom decimal separator, supports leading 0, regexp

Hello, Due to the success on my precedent post, I try again to get some comments on my precedent patch and some new things I need in ext/filer. This patch adds or changes the following things: - regexp uses functions (ext/pcre) - 100% compatible with preg_* functions - Use of expression caches and other (faster) - Regexp tests now work - rewrite the filter_float - support custom decimal separator. Let the developer decides which separator to use, the default is not changed - slightly faster than the old implementation (and with the new features) The patch: http://pear.php.net/~pierre/filter_float_add_custom_seps_and_pcre.txt Some examples: http://pecl.php.net/~pierre/filter_float.phps Any ideas or comments are welcome, --Pierre
