[syslog-ng] Unable to compile version 1.6.12 on Solaris 9

[roel at raphor.net]

I'm trying to compile syslog-ng-1.6.12 on Solaris 9.
This aborts with the following error:

gcc  -g -O2 -Wall -I/usr/local/src/syslog-ng-1.6.12/libol-0.3.18/src

make[1]: *** [all] Error 2
make[1]: Leaving directory `/usr/local/src/syslog-ng-1.6.12/src'
make: *** [all-recursive] Error 1

Whereas syslog-ng-1.6.11 compiles without any problems.
Any suggestions?


Cheers,
