Log:
  Remove obsolete check for GCC < 3 and support for Intel Compiler
  
  We no longer support old versions of GCC. Remove this check by
  assuming it's false. That will make the entire expression false.  Also
  remove support for Intel compiler, it's badly bitrotted.  Technically,
  this removes support for C89 and K&R from compilers that don't define
  _Bool in those compilation environments as well. I'm unaware of any
  working compiler today for which that would be relevant (pcc has it
  and tcc sadly isn't working for other reasons), though if one
  pops up in ports, I'll work to resolve the issue.
