Hi Markus,

ESRCH is POSIX.1 and defined in sys/errno.h on most standardized
systems. 
On IRIX: errno.h:#define ESRCH   3 /* no such process */.

But many quirky systems have no or incomplete header-files installed. 

But as Roberto Flor said, this is a problem of the system, no general
compiler or program error. You should verify that errno.h is included in
the source (#include <sys/errno.h>). Everything else is on the users
side.
