(nice_to_winprio): Ditto. * pinfo.cc (pinfo_init): If parent is not a Cygwin process, set default nice value according to current Win32 priority class. * pinfo.h (class _pinfo): Add nice member. * syscalls.cc (setpriority): New function, only implementing PRIO_PROCESS for now. (getpriority): Ditto. (nice): Just call setpriority. * wincap.h (wincaps::has_extended_priority_class): New element. * wincap.cc: Implement above element throughout. * winsup.h: Add prototypes for winprio_to_nice and nice_to_winprio. * include/limits.h (NZERO): New define. * include/cygwin/types.h (id_t): New datatype. * include/cygwin/version.h: Bump API minor version. * include/sys/resource.h: Add PRIO_XXX defines and prototypes for getpriority and setpriority.
