[syslog-ng]compiling syslog-ng (latest version) on solaris 9 - error

[Markus Reger]

hello to everybody

Made several attempts to compile syslog-ng. Compilation of libol went =
fine. Whenever I "make" syslog-ng I encounter the error:

Has anyone ever compiled on Solaris 9 - gcc 3.3.=20
Thanks in advance for every hint.
