#2000: boost/detail/spinlock_sync.hpp incorrectly included for Intel C++ on Linux

     Type:  Bugs          |      Status:  new       
Milestone:  Boost 1.36.0  |   Component:  smart_ptr 
  Version:  Boost 1.35.0  |    Severity:  Regression
 Keywords:                |  
--------------------------+-------------------------------------------------
 On a linux-x86_64 system with gcc 4.1.3 and Intel 10.1, an include of
 boost/shared_ptr.hpp pulls in boost/detail/spinlock_sync.hpp, which fails
 to compile since the __sync functions are undefined.

 It appears this problem is due to the #if sequence in
 boost/detail/spinlock.hpp. The Intel compiler defines __GNUC__ and
 __GNUC_MINOR__, but doesn't provide the intrinsics.

 By adding "&& !defined(BOOST_INTEL)" to the appropriate #if line as in the
 attached patch, everything works.
