>Description:

When I compile and link a trivial C++ program, I get undefined references
to std::errno.  This happens on native Solaris 2.5.1.  It does not happen
on native Red Hat Linux 6 or native Red Hat Linux 7.

This worked on native Solaris 2.5.1 on 2001-03-25, so the problem happened
between 2001-03-25 and 2001-03-31.

>How-To-Repeat:

Source program:

  #include <iostream.h>

  int main ()
  {
    return 0;
  }

Command line:

  % g++ -v x2.cc
