Hello,

I'm trying to install gcc-4.7 and have problems with the posix threads,
especially with the PTHREAD_ONCE_INIT decalration in the pthread.h file.
When installing, it often ends up with this 

error: ‘PTHREAD_ONCE_INIT’ undeclared here (not in a function)  static
pthread_once_t create_key_once = PTHREAD_ONCE_INIT;

So, it would be very helpful to understand what the definition of
"PTHREAD_ONCE_INIT" is about. If it's a fixed size or address value and what
it's role when handling threads. 
Moreover there are some different versions of pthread. The one wich created
the error above, i can't find now.
