See the config manual and look for $shell |

Stefan, I found the following "forkpty()" replacement for running under Solaris. The URL is http://www.developerweb.net/forum/showthread.php?t=2990.
Perhaps this can be used unless someone comes up with a Solaris "util" library.
#ifdef SOLARIS /* Use the code in my_forkpty.c */
int my_forkpty (int *amaster, char *name, void *unused1, void *unused2);
#define forkpty my_forkpty
#endif

#include <sys/stream.h>
#include <sys/stropts.h>
/* fork_pty() remplacement for Solaris.
* This ignore the last two arguments

int
my_forkpty (int *amaster,

return -1;
