Milter-greylist

Have been a while absent, everything concerning milter-greylist just 
running fine :-) 
Now I'm rolling out our first servers with CentOS 4.2 and hit a compile 
problem, make says:

gcc -g -O2 -Wall -I/usr/pkg/include -D_BSD_SOURCE   -c -o 
milter-greylist.o milter-greylist.c
In file included from acl.h:51,
                 from milter-greylist.c:71:
pending.h:75: error: syntax error before "pending_lock"
pending.h:75: warning: type defaults to `int' in declaration of 
`pending_lock'
pending.h:75: warning: data definition has no type or storage class


As I know some here are running CentOS, so can anyone shed some light on 
this error and how to fix it?

That line is "extern pthread_rwlock_t pending_lock;" Could this be a 
thread-safety issue? I installed lib_spf2 for spf as I always do. I can't 
believe the Suse Linux resolver is thread-safe but the CentOS/RHEL one is 
not. Do I need to install some library (sendmail-devel is installed)?

An issue with gcc?

Thanks!

Kai
