threads branch: is 'include/parrot/atomic/gcc_pcc.h' named correctly?

[James E Keenan]

This file is one of several which is found only in the threads branch. 
It describes its purpose as follows:

  *     This header provides an implementation of atomic
  *     operations on PowerPC platforms with GCC-style
  *     inline assembly suppport.

Given that, why isn't the file's basename 'gcc_ppc.h'?  And shouldn't 
'pcc' be changed to 'ppc' in these locations?

$ ack -i pcc include/parrot/atomic/gcc_pcc.h
/* atomic/gcc_pcc.h
include/parrot/atomic/gcc_pcc.h
#ifndef PARROT_ATOMIC_GCC_PCC_H_GUARD
#define PARROT_ATOMIC_GCC_PCC_H_GUARD
#endif /* PARROT_ATOMIC_GCC_PCC_H_GUARD */

Thank you very much.
