Hi,

  g++ pollutes the global namespace. The following does not compile with G++
4.4.5:


#include <iostream>
int truncate = 0;
int main()
{
  return 0;
}

If fails with:


t.cxx:2: error: âint truncateâ redeclared as different kind of symbol
/usr/include/unistd.h:998: error: previous declaration of âint truncate(const
char*, __off_t)â


Thanks !
