Fixes bootstrap and regression tests cleanly.  Ok to commit.

Nothing to be sorry about!  Things can break
at the top-of-tree.  Plus, I learned something,
from the linux pthread_self() man page:

  POSIX.1 allows an implementation wide freedom in choosing the type
  used to represent a thread ID; for example, representation using
  either an arithmetic type or a structure is permitted.  Therefore,
  variables of type pthread_t can't portably be compared using the C
  equality operator (==); use pthread_equal(3) instead.

  Thread identifiers should be considered opaque: any attempt to use
  a thread ID other than in pthreads calls is nonportable and can
  lead to unspecified results.
