[syslog-ng]syslog-ng and Redhat 7.3

Hello List, I tried to install/compile syslog-ng vers. 15.18 on to my RH 7.3 System. My System is using glibc vers. 2.5.5 While compiling a lot of errors occurred, so I could not run syslog-ng. Is syslog-ng vers. 15.18 not compatible with RH 7.3 and libc vers. 2.5.5? Does any body has any answer for that question? It is my intention to setup an win-nt40-eventlog-messages collecting linux server which keeps all NT-Eventlog from my network send by EventReporter. I just want to use the enhanced features of syslog-ng for that project. Thanx for helping in advance Kai
