integration fix: fixes for pthread_getname_np

- define _GNU_SOURCE before including pthread.h
- do not use static for the array 'threadname' used
  to store the name, it makes it a global variable
  accessed by several threads in parallel
- increase size of 'threadname' (maybe not necessary)
- properly indent #define / #under (# should be at column 1)
