[CentOS] Problem with gettid() on CentOS 5/gcc 4.1.1

[Alfred von Campe]

Could someone with access to a RHEL 5 system please post the output  
of the following command:

   grep -RE "#define[[:space:]]+_syscall" /usr/include

I'd like to know if this problem affects RHEL 5 as well.

Thanks,
Alfred
