With PHP 5.3 I started to recieve

Fatal error: Only variables can be passed by reference

when trying to call idn_to_ascii with second optional parameter (IDNA_DEFAULT).
Moreover these IDNA_* constants are seem to be undefined in PHP 5.3. + PECL idn 0.0.2

When I tried to uninstall PECL idn and install PECL intl (1.1.1) i recieved this:

/tmp/pear/temp/intl/collator/collator_class.c:92: error: duplicate ‘static’
/tmp/pear/temp/intl/collator/collator_class.c:96: error: duplicate ‘static’
/tmp/pear/temp/intl/collator/collator_class.c:101: error: duplicate ‘static’
/tmp/pear/temp/intl/collator/collator_class.c:107: error: duplicate ‘static’
make: *** [collator/collator_class.lo] Error 1

So probably compiling PHP 5.3. from sources with --enable-intl will help, but it only means that PHP 5.3. intl version differs from the one available at PECL, which isn't good, I think.

I've made my code working again by giving second idn_to_ascii parameter as simple integer variable (with value 0), but something bad is going on here and i will not be surprised if it'll break again after another PHP update...
