    sync/atomic: use strong form of atomic_compare_exchange_n
    
    In the recent change to use atomic_compare_exchange_n I thought we
    could use the weak form, which can spuriously fail. But that is not
    how it is implemented in the gc library, and it is not what the rest
    of the library expects.
    
    Thanks to Lynn Boger for identifying the problem.

See ../README.

This is the runtime support library for the Go programming language.
This library is intended for use with the Go frontend.

This library should not be stripped when it is installed.  Go code
relies on being able to look up file/line information, which comes
from the debugging info using the libbacktrace library.

The library has only been tested on GNU/Linux using glibc, and on
Solaris.  It should not be difficult to port to other operating
systems.

Directories:

go
  A copy of the Go library from http://golang.org/, with several
  changes for gccgo.

runtime
  Runtime functions, written in C, which are called directly by the
  compiler or by the library.
