  Avoid sizeof __func__ == 0 pitfall.

  @section func
  
  The @code{func} module makes sure that you can use the predefined
  identifier @code{__func__} as defined by C99 in your code.
  
  A small example is:
  
  @smallexample
  #include <config.h>
  #include <stdio.h> /* for printf */
  
  int main (void)
  @{
      printf ("%s: hello world\n", __func__);
  @}
  @end smallexample
  
  Note that @code{sizeof} cannot be applied to @code{__func__}: On SunPRO C
  compiler, @code{sizeof __func__} evaluates to 0.
