I can't get the simple program below to compile on CentOS 5 beta. It compiles (and runs) just fine on CentOS 4.4, and I'm using gettid() as described in the man page. I wonder if this is a problem with RHEL 5 as well, but I don't have a system to test on. I also wonder if this is a gcc 4.1.1 issue or something missing in CentOS 5.
The issue is that the _syscall0 macro is not defined anywhere. If I copy and paste the following definition for _syscall0 from a CentOS 4.4 system into the test program, it works just fine:
#define _syscall0(type,name) \ type name(void) \ {\ return syscall(__NR_##name);\ }
Has anyone else run into this problem?

I've got an APP at work that will need to be working on RH5 and possibly Centos 5 that uses gettid(), so I'm going to hang onto your posting just in case it is a problem in the real release. Haven't tried RH5 yet, but I will be (and Centos, too, once it comes out).
Thanks for the heads-up.
