--with-zend-multibyte safe/useable?

Hi PHP devs, I'm Luca Longinotti, one of the PHP maintainers in Gentoo.
I tought I'd ask about this here as to have some input from the people
developing this, since I never used that particular configure option
before...
Basically, we have a request from a user to add --with-zend-multibyte to
our PHP packages ( https://bugs.gentoo.org/show_bug.cgi?id=130154 ), for
who knows Gentoo and is intersted, it would be under the "unicode" USE flag.
Now, I wasn't able to find any more documentation about that particular
option, if not the ./configure --help output, and the linked PHP bug (
http://bugs.php.net/bug.php?id=22108 ). So my question is: would it be
safe to add --with-zend-multibyte as option to our PHP packages, is that
safe/useable at all, or will it break other things?

Depending on what you have currently in the "unicode" USE flag I would
say. This multibyte switch has not much to do with unicode, nor would I
recommend it for normal production sites unless you really need it. So
if the unicode flag now contains "mbstring" for example, don't add it.
It's probably the best to make it a new USE flag.

regards,
Derick
