v4.2.3 compliant sybase_set_message_handler

Hi *, i'm using PHP 4.2.3 on a Linux box with sybase_ct compiled as a shared object and i *really* need that sybase_set_message_handler function from PHP > 4.3.0, but there's no chance to recompile the complete PHP binaries at the moment. So i tried to copy & paste the needed function into the 4.2.3 sources... didn't work (as i expected). Here is what 'make' says: -- 8< -- php_sybase_ct.c: In function `zif_sybase_set_message_handler': php_sybase_ct.c:1722: warning: assignment makes pointer from integer without a cast php_sybase_ct.c:1729: structure has no member named `callback_name' php_sybase_ct.c:1730: structure has no member named `callback_name' php_sybase_ct.c:1731: structure has no member named `callback_name' php_sybase_ct.c:1746: structure has no member named `callback_name' php_sybase_ct.c:1747: structure has no member named `callback_name' php_sybase_ct.c:1748: structure has no member named `callback_name' php_sybase_ct.c:1748: structure has no member named `callback_name' php_sybase_ct.c:1749: structure has no member named `callback_name' make[3]: *** [php_sybase_ct.slo] Error 1 make[3]: Leaving directory `/home/kehr02/dev/php-4.2.3/ext/sybase_ct' make[2]: *** [all-recursive] Error 1 make[2]: Leaving directory `/home/kehr02/dev/php-4.2.3/ext/sybase_ct' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/home/kehr02/dev/php-4.2.3/ext' make: *** [all-recursive] Error 1 -- >8 -- What have i done wrong? Thanks for reading this message :-) Regards, Nils.
