[linux] OT: g++2.95/3.2 and ambiguous overload

[Peter Mikula]

hello,

  prilozeny kod sa da skompilovat na g++2.95.3 bez problemov, ale na
  g++3.2 to zdochne s:

      ambig.cc: In function `int main()':
      ambig.cc:25: ambiguous overload for `AmbigTest& << const char[21]' operator
      ambig.cc:10: candidates are: AmbigTest AmbigTest::operator<<(C) [with C = const char*]
      ambig.cc:16:                 AmbigTest AmbigTest::operator<<(const C&) [with C = char[21]]

  je mi jasne o com ta chyba je, ale neviete niekto ako sa to da obist ? 
  Da sa nejako definovat precedence, ze by som povedal ze chcem pouzit 
  referenciu ked je to mozne ... ?

                                         magic is insufficiently advanced
