04-implicit-pointer-conversions.dpatch by Martín Ferrari <martin.ferrari@gmail.com>

http://sourceforge.net/support/tracker.php?aid=1744571

 Patch for correct declaration of types and functions. Missing includes,
 forward declarations and also I had to replace getpt with posix_openpt,
 because for some obscure reason it was not being defined. Anyway,
 posix_openpt is the portable way of doing it.
