use stl_algo.h-fixed for GCC 4.8.0 and 4.8.1 if nth_element bug is detected * acinclude.m4 (OCTAVE_CHECK_BROKEN_STL_ALGO_H): If nth_element test fails and we are using GCC 4.8.0 or 4.8.1, then don't reset octave_cv_broken_stl_algo_h. Someone may have patched their 4.8.0 or 4.8.1 GCC with the buggy performance patch for 4.8.2. Ubuntu, I'm looking at you.

#include "mex.h"

void
mexFunction (int nlhs, mxArray *plhs[],
             int nrhs, const mxArray *prhs[])
{
  const char *nm;

  nm = mexFunctionName ();
  mexPrintf ("You called function: %s\n", nm);
  if (strcmp (nm, "myfunc") == 0)
    mexPrintf ("This is the principal function\n", nm);

  return;
}
