$ cat bug.cc

#include <istream>

void f(std::ios_base::seekdir dir)
{
  switch (dir) {
  case std::ios_base::beg:
    break;
  case std::ios_base::cur:
    break;
  case std::ios_base::end:
    break;
  }
}

$ LANG=C g++-3.4.2 -Wall -c bug.cc 
bug.cc: In function `void f(std::_Ios_Seekdir)':
bug.cc:12: warning: enumeration value `_S_ios_seekdir_end' not handled in switch
bug.cc:12: warning: case value `0' not in enumerated type `_Ios_Seekdir'
bug.cc:12: warning: case value `1' not in enumerated type `_Ios_Seekdir'
bug.cc:12: warning: case value `2' not in enumerated type `_Ios_Seekdir'

These warnings are not very usefull: the code cover all the standard
values and only them but the compiler complaim about missing value and values
not in the type.

Yours,
