#30558 [Asn]: mbstring mbregex failure to compile pointer cast problems
ID: 30558 Updated by: [EMAIL PROTECTED] Reported By: jbarwick at sentienthealth dot com Status: Assigned Bug Type: Compile Failure Operating System: SuSE 9.1 (amd64) PHP Version: 4.3.8 Assigned To: moriyoshi New Comment: Just a note, I'm currently working on this. Stay tuned. Previous Comments: [2004-11-04 14:43:49] [EMAIL PROTECTED] Grrr, fixing version/OS again. [2004-11-04 14:37:07] [EMAIL PROTECTED] I'm not sure if jbarwick's suggested fix: The changed all "int"'s to "MINT" and changed all "long"'s to "MLONG" is really advisable; Moriyoshi, have you looked at this?
