Log:
  cdefs.h: remove intel_compiler support
  
  The  age  of   the  intel  compiler  support  is  so   old  as  to  be
  uninteresting. No recent recports of  intel compiler support have been
  received.  Remove  all the  special  case  workarounds for  the  Intel
  compiler. Should there be interest in supporting the compiler, contact
  me and I'll work with people to make it happen, though I suspect these
  instances are more likely to be in the way than to be helpful.
